Works similar to ex <f-args>. It only splits the arguments if the
command has more than one posible argument. In cases were the command
can only have 1 argument opts.fargs = { opts.args }
Looks like I did an oopsie; although API strings carry a size field, they should
still be usable as C-strings! (even though they may contain embedded NULs)
nvim_buf_set_text does not handle negative row numbers correctly: for
example,
nvim_buf_set_text(0, -2, 0, -1, 20, {"Hello", "world"})
should replace the 2nd to last line in the buffer with "Hello" and the
first 20 characters of the last line with "world". Instead, it reports
"start_row out of bounds". This happens because when negative line
numbers are used, they are incremented by one additional number to make
the non-negative line numbers end-exclusive. However, the line numbers
for nvim_buf_set_text should be end-inclusive.
In #15181 we handled this for nvim_buf_get_text by adding a new
parameter to `normalize_index`. We can solve the problem with
nvim_buf_set_text by simply availing ourselves of this new argument.
This is a breaking change, but makes the semantics of negative line
numbers much clearer and more obvious (as well as matching
nvim_buf_get_text).
BREAKING CHANGE: Existing usages of nvim_buf_set_text that use negative
line numbers will be off-by-one.
Nvim uses a floating window for the autocmd window, but in certain situations,
it can be made non-floating (`:wincmd J`), which can cause issues due to the
previous setup and cleanup logic for a non-floating aucmd_win being removed from
aucmd_prepbuf and aucmd_restbuf.
This can cause glitchiness and crashes due to the aucmd_win's frame being
invalid after closing its tabpage, for example.
Ensure aucmd_win cannot be made non-floating. The only place this happens is in
win_split_ins if new_wp != NULL.
nvim_buf_get_text is the mirror of nvim_buf_set_text. It differs from
nvim_buf_get_lines in that it allows retrieving only portions of lines.
While this can typically be done easily enough by API clients,
implementing this function provides symmetry between the get/set
text/lines APIs, and also provides a nice convenience that saves API
clients the work of having to slice the result of nvim_buf_get_lines
themselves.
Problem: Integer overflow with large line number.
Solution: Check for overflow. (closesvim/vim#9202)

Put E1247 in globals.h as E1240 is also there.
Do not make getdigits() abort.
Problem: when accessing `nvim_set_hl` from Lua, empty tables are converted
to empty lists, not dictionaries, resulting in an error for
:lua vim.api.nvim_set_hl(0, "Comment", { cterm = {} })
Workaround: add an empty array as a special case when checking
`dict->cterm.type` and just set `cterm_mask_provided`.
(Proper solution: handle this in `gen_api_dispatch.lua`.)
Problem: Check for overflow in put count does not work well.
Solution: Improve the overflow check. (Ozaki Kiichi, closesvim/vim#9102)

Add some casts as Nvim uses size_t variables in some places.
We could technically adjust the logic to check for overflow outside of size_t's
range, but it's much easier to just port the patch exactly (also means we can
use the same tests).
v:sizeoflong is N/A, so convert the 64-bit tests to Lua and use the FFI to check
long's size.
Add tests for:
- Cursor position restored after :map expr
- Cursor position restored after :imap expr
- Error in :cmap expr handled correctly
