Problem: Alloc() returning "char_u *" causes a lot of type casts.
Solution: Have it return "void *". (Mike Williams) Define ALLOC_ONE() to
check the simple allocations.
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: Cannot recover from a swap file.
Solution: Do not expand environment variables in the swap file name.
Do not check the extension when we already know a file is a swap
file. (Ken Takata, closes 4415, closes#4369)
Problem: No error for quickfix commands with negative range.
Solution: Add ADDR_UNSIGNED and use it for quickfix commands. Make
assert_fails() show the command if the error doesn't match.
Problem: Cannot navigate through errors relative to the cursor.
Solution: Add :cabove, :cbelow, :labove and :lbelow. (Yegappan Lakshmanan,
closes#4316)
Problem: Ex command info contains confusing information.
Solution: When using the NOTADR flag use ADDR_OTHER for the address type.
Cleanup code using NOTADR. Check for errors in
create_cmdidxs.vim. Adjust Makefile to see the errors.
Problem: Support for user commands is spread out. No good reason to make
user commands optional.
Solution: Move user command support to usercmd.c. Always enable the
user_commands feature.
Problem: Decoding of mouse click escape sequence is not tested.
Solution: Add a test for xterm and SGR using low-level input. Make
low-level input execution with feedkeys() work.
Problem: reg_executing() is reset by calling input().
Solution: Implement a more generic way to save and restore reg_executing.
(Ozaki Kiichi, closes#4192)
Problem: Macros for MS-Windows are inconsistent, using "32", "3264 and
others.
Solution: Use MSWIN for all MS-Windows builds. Use FEAT_GUI_MSWIN for the
GUI build. (Hirohito Higashi, closes#3932)
Problem: Can execute shell commands in rvim through interfaces.
Solution: Disable using interfaces in restricted mode. Allow for writing
file with writefile(), histadd() and a few others.
Problem: Cannot have a local value for 'scrolloff' and 'sidescrolloff'.
(Gary Holloway)
Solution: Make 'scrolloff' and 'sidescrolloff' global-local. (mostly by
Aron Widforss, closes#3539)
Problem: When using VTP wrong colors after a color scheme change.
Solution: When VTP is active always clear after a color scheme change.
(Nobuhiro Takasaki, closes#3872)
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: Tabline is not always redrawn when something that is used in
'tabline' changes.
Solution: Add ":redrawtabline" so that a plugin can at least cause the
redraw when needed.
Problem: DirChanged is also triggered when the directory didn't change.
(Daniel Hahler)
Solution: Compare the current with the new directory. (closes#3697)
Problem: :digraph output is not easy to read.
Solution: Add highlighting for :digraphs. (Marcin Szamotulski, closes#3572)
Also add section headers for :digraphs!.
Problem: Cannot use address type "other" with with user command.
Solution: Add "other" to the list. (Daniel Hahler, closes#3655) Also
reject "%" for commands with "other". Add some more tests.
