Problem: Match highlighting marks a buffer region to be redrawn as if
its buffer text was changed, unnecessarily invoking syntax code.
Solution: Set the `w_redraw_top/bot` variables instead of the b_mod_* ones

Problem: marker folds may get corrupted on undo (Yousef Mohammed)
Solution: when adjusting folds, make sure that line1 is the lower limit
and line2 is the upper line limit. In particular, line2 should
not be able to get smaller than line1.

Problem: Coverity reports dead code.
Solution: Remove the dead code. Also fix a mistake in ml_get_pos_len()
and update some comments (zeertzjq).

Problem: More code can use ml_get_buf_len() instead of STRLEN().
Solution: Change more STRLEN() calls to ml_get_buf_len(). Also do not
set ml_line_textlen in ml_replace_len() if "has_props" is set,
because "len_arg" also includes the size of text properties in
that case. (zeertzjq)

Problem: a closing fold expression may unexpectedly start a new fold
when it should end a fold
(reported by Shota Nozaki)
Solution: if a fold hasn't started yet, do not immediately
start a new fold with level 1

Problem: Evaluating "expr" options has more overhead than needed.
Solution: Use call_simple_func() for 'foldtext', 'includeexpr', 'printexpr',
"expr" of 'spellsuggest', 'diffexpr', 'patchexpr', 'balloonexpr',
'formatexpr', 'indentexpr' and 'charconvert'.
Problem: With 'foldmethod' "indent" some lines are not included in the
fold. (Oleg Koshovetc)
Solution: Fix it. (Brandon Simmons, closes#10399, closes#3214)
Problem: Cannot use an import in 'foldexpr'.
Solution: Set the script context to where 'foldexpr' was set. (closes#9584)
Fix that the script context was not set for all buffers.
Problem: Vim9: runtime and compile time type checks are not the same.
Solution: Add more runtime type checks for builtin functions. (Yegappan
Lakshmanan, closes#8646)
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.
Problem: In diff mode global operations can be very slow.
Solution: Do not call diff_redraw() many times, call it once when redrawing.
And also don't update folds multiple times.
Problem: Ml_get error when deleting fold marker.
Solution: Check that the line number is not below the last line. Adjust the
fold when deleting the empty line. (Christian Brabandt,
closes#4834)
Problem: Using "int" for alloc() often results in compiler warnings.
Solution: Use "size_t" and remove type casts. Remove alloc_check(), Vim
only works with 32 bit ints anyway.
Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
