Problem: buffer-overflow in vim_regsub_both()
Solution: Check remaining space
ced2c7394a
The change to do_sub() looks confusing. Maybe it's an overflow check?
Then the crash may not be applicable to Nvim because of different casts.
The test also looks confusing. It seems to source itself recursively.
Also don't call strlen() twice on evaluation result.
N/A patches for version.c:
vim-patch:9.0.1849: CI error on different signedness in ex_cmds.c
vim-patch:9.0.1853: CI error on different signedness in regexp.c

ml_get_buf() takes a third parameters to indicate whether the
caller wants to mutate the memline data in place. However
the vast majority of the call sites is using this function
just to specify a buffer but without any mutation. This makes
it harder to grep for the places which actually perform mutation.
Solution: Remove the bool param from ml_get_buf(). it now works
like ml_get() except for a non-current buffer. Add a new
ml_get_buf_mut() function for the mutating use-case, which can
be grepped along with the other ml_replace() etc functions which
can modify the memline.
problem: breakcheck might run arbitrary lua code, which might require
modules and thus invoke runtime path calculation recursively.
solution: Block the use of breakcheck when expanding glob patterns
inside 'runtimepath'

Problem: Vim9: leaking memory when using continuation line.
Solution: Keep a pointer to the continuation line in evalarg_T. Centralize
checking for a next command.

Using sizeof seems better than ARRAY_SIZE for vim_snprintf().
Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: No error if engine selection atom is not at the start.

This is a refactor extracted from vim-patch 9.0.0067: cannot show virtual text
The logic for inline virtual text is going to be different in nvim than
text property based text in vim, but this refactor is still useful,
as calculation of displayed linesize is going to be stateful in a
similar way.
Problem: Profiling functionality is spread out.
Solution: Put profiling functionality in profiling.c. (Yegappan Lakshmanan,

Move proftime_T to types.h for now to avoid recursive #include.
