zeertzjq fadf5fc8db vim-patch:9.2.0024: Reading files with very long lines crashes with a segfault

Problem:  Reading files with lines approaching MAXCOL length crashes
          with segfault due to colnr_T overflow.
Solution: The split check 'linerest >= MAXCOL' fired too late because
          linerest could grow by up to 'size' bytes before the next
          check. Change threshold to 'linerest >= MAXCOL - size' to
          ensure the line passed to ml_append() stays within colnr_T
          range.
