Subject: [PATCH] fix(vim-patch.sh): don't treat 1-file runtime-only patch as
 N/A (#36525)

If the patch in question does not change src/version.c, `git log -1`
instead shows the previous patch that changes src/version.c, which
causes 1-file runtime-only patches to be considered N/A.

Check that the remaining file is src/version.c to fix this problem.
Also use `git diff-tree` instead of `git log -1` for version.c.
