49c19a1fe3 fix(messages): message not flushed at end of command #37904
Problem:  Logic determining messages belonging to the last command to
          show with "g<" does not flush pending messages. This can
          result in clearing the temporary message history before a
          message still belonging to the previous command was emitted.
Solution: Flush pending messages when marking the end of messages
          belonging to previous command.

501a21f333 fix(coverity/637363): out-of-bounds write #37878
Problem:
stack->offset value is used as an array index.

Solution:
Instead of comparing the stack->offset value to the size in bytes of the array,
compare the actual length of the array.

a393347673 fix(extmark): adjust invalidate range by one for deleted lines #37897
Problem:  A multi-line extmark that ends exactly at a deleted range end
          is not invalidated.
          Revalidated sign mark is added with incorrect range.
Solution: Remove questionable invalidation range condition which was
          originally added to avoid deleting a mark that ends below a
          deleted line.

          Since splicing for a deleted line, and a replaced range that
          explicitly ends at column 0 beyond a deleted line is identical,
          we can't try to distinguish these two cases. I.e. :1delete 1
          and nvim_buf_set_text(0, 0, 0, 1, 0, {}) yield the same splice
          operation.

          This means that a multi-line sign_text mark should now span at
          least one column beyond its end_row, as seen in the adjusted
          test. This is still somewhat unexpected/inconvenient to me
          which is what prompted me to try to avoid it with the original
          condition.

          Add revalidated sign mark back to decor with correct range;
          third sign mark added to test exposed a crash.

Problem:  A float whose zindex is below the cmdline can be enlarged and

e6fae64454 fix(terminal): handle opening terminal on unloaded buffer (#37894)
Problem:  Strange behavior when opening terminal on unloaded buffer.
Solution: For nvim_open_term() ensure the buffer is loaded as it needs
          to be read into the terminal. For jobstart() just open the
          memfile as the file content isn't needed.

Not going to make nvim_open_term() pass stdin to the terminal when stdin
isn't read into a buffer yet, as other APIs don't read stdin on unloaded
buffer either. There are also other problems with loading buffer before
reading stdin, so it's better to address those in another PR.

51dc752e6c fix(prompt): wrong changed lnum in init_prompt
Problem: if init_prompt replaces the prompt line at the ': mark, it calls
inserted_bytes with the wrong lnum.

3a10405214 fix(prompt): prompt_setprompt does not adjust extmarks, no on_bytes
Problem: prompt_setprompt does not adjust extmarks or trigger on_bytes
buffer-updates when fixing the prompt line.

Solution: adjust them, trigger on_bytes.

Notably, hides extmarks when replacing the entire line (and clearing user
input). Otherwise, when just replacing the prompt text, hides extmarks there,
but moves those after (in the user input area) to the correct spot.

7641177c5f fix(prompt): wrong cursor col after prompt_setprompt, no on_lines
Problem: prompt_setprompt calls coladvance with a byte column, but it expects a
screen column. on_lines buffer-updates aren't fired when fixing the prompt line.

Solution: don't use coladvance. Call changed_lines, which also simplifies the
redraw logic. (and calls changed_cline_bef_curs if needed; added test checks
this)

Unlike https://github.com/neovim/neovim/pull/37743/changes#r2775398744, this
means &modified is set by prompt_setprompt if it fixes the prompt line.
Not setting &modified is inconsistent anyway -- even init_prompt sets it if it
fixes the prompt line.

b614c15392 refactor(terminal): don't put cursor at bottom-left in Normal mode (#37873)
When the terminal process is suspended, putting cursor at bottom-left
hints that pressing a key will change the suspended state. However, when
returning to Normal mode, the user is more likely to interact with the
actual terminal output (e.g. copying it), so it's better to put cursor
at the old position which should be closer to the output.

Also, using is_focused() to check for mode is confusing. Just check
`State & MODE_TERMINAL` instead.

8ab511bba5 feat(prompt): plugins can update prompt during user input #37743
Problem:
Currently, if prompt gets changed during user-input with
prompt_setprompt() it only gets reflected in next prompt. And that
behavior is not also consistent. If user re-enters insert mode then the
user input gets discarded and a new prompt gets created with the new
prompt.

Solution:
Handle prompt_setprompt eagerly. Update the prompt display, preserve user input.

a7177e34c3 fix(highlight): link HLF_8 to something more prominent #34910
Problem:
HLF_8 is used by :intro and :map. And none of the other HLF_x things
use the other Special groups. So we have a darkgray highlight that's
very common, and not easy to read.

Darkgray makes sense for "Conceal", "non-printing chars", etc. But not
for keycodes or similar common elements.

Solution:
Link SpecialKey to Special.

0864939cc5 fix(restart): append -c <cmd> at end, drop -- [files…] #37846
Problem:
- `:restart <cmd>` prepends `-c <cmd>` before the original `-c` args (if
  any). So the original `-c` args may "override" it, which is
  surprising.
- Confusing logic: `v:argv` is partially prepared in `ex_docmd.c`, and
  then later `ui.c` skips other parts of it.

Current behavior is nonsense, for example this sequence:

    :restart echo "Hello"
    :restart +qall echo "Hello" | echo "World"

results in this v:argv:

    [
      'nvim'
      '-c'
      'echo "Hello" | echo "World"'
      '--embed'
      '-c'
      'echo "Hello"'
      ...
    ]

Whereas after this commit, v:argv is:

    [
      'nvim'
      '--embed'
      ...
      '-c'
      'echo "Hello" | echo "World"'
    ]

Solution:
- Append `-c <cmd>` at the _end_ of `v:argv`, not the start.
- Use a dummy placeholder `+:::` to mark where the "restart command"
  appears in `v:argv`.
- Do all `v:argv` preparation in `ex_docmd.c`. This simplifies `ui.c`.
- Drop `-- [files…]` from `v:argv` since it is probably more annoying
  than useful. (Users can use sessions to restore files on restart.)

6657cc3671 fix(ui): repaint separator connectors after all window updates #37852
Problem:
When a window is redrawn, `draw_vsep_win`/`draw_hsep_win` paint plain
separator characters (`│`/`─`) along the window's entire edges,
including cells that are connector corners belonging to other windows.
Then `draw_sep_connectors_win` only fixes the corners of that same
window, not connectors in the middle of its edges that belong to
adjacent windows.

If the window that "owns" the connector corner isn't part of the redraw,
the connector is never repainted.

Solution:
Move connector drawing out of the per-window `win_update` and into a
separate pass in `update_screen` that runs after all windows have been
updated.

88dc44260f fix(api): preserve WinConfig style when converting float to split #37264
Problem: When a float window with style='minimal' is converted to a
split window and then changes buffer, the minimal style options get
overridden. This happens because merge_win_config() clears the style
field, so get_winopts() doesn't know to re-apply minimal style after
restoring options from the buffer's wininfo.

during float-to-split conversion.

fa24df3264 fix(bufwrite.c): handle invalid byte sequences #37363
Problem:

bw_rest was used as an extra buffer to save incomplete byte sequences
between calls to buf_write_bytes. Besides being unnecessarily
complicated, this introduced a number of issues:

1) The bytes stored in bw_rest could still be there at the end of
writing the file, never having been written, thus losing some of the
file content on write.

2) bw_rest was not cleared out after the "checking_conversion" phase,
leaving them to affect the written file content during the writing
phase, corrupting the file.

3) bw_rest could contain extra bytes that need to be written to the
output buffer during a buf_write_convert call, potentially before any
bytes are consumed. But some conversions are in-place, without a
separate output buffer. Writing bytes from bw_rest to the "output"
buffer actually overwrote bytes from the input buffer before they were
read, corrupting the data to be written.

4) The extra bytes in bw_rest that need to be written to the conversion
output buffer were not originally accounted for in the size calculation
for the output buffer, causing a buffer overflow (previously fixed in
Vim patch 9.1.2028).

Solution:

Rather than maintaining a separate buffer, the unconverted bytes at the
end of the buffer can just be shifted to the beginning of the buffer,
and the buffer size updated. This requires a bit of refactoring, and
buf_write_convert and buf_write_convert_with_iconv need to report the
number of bytes they consumed so that buf_write_bytes can handle the
remaining bytes.

Following conversion, bw_buf can be checked for any remaining bytes.
Leftover bytes in this case result in a conversion error, which is
better than silently dropping them.

A short section of dead code was removed from buf_write_convert, for
converting a non-UTF-8 buffer to UTF-8. Neovim buffers are always UTF-8.

A few additional tests for iconv conversions have been added. Vim's
iconv tests are disabled in Neovim because they use unsupported values
for 'encoding'.

6b4ec2264e feat(stdlib): vim.json.decode() can allow comments #37795
Problem:
`vim.json.decode()` could not parse JSONC (JSON with Comments)
extension, which is commonly used in configuration files.

Solution:
Introduce an `skip_comments` option, which is disabled by default. When
enabled, allows JavaScript-style comments within JSON data.
