Problem: The "last used" info of a buffer is under used.
Solution: Add "lastused" to getbufinfo(). List buffers sorted by last-used
field. (Andi Massimino, closes#4722)
Problem: When editing a buffer 'colorcolumn' may not work.
Solution: Set the buffer before copying option values. Call
check_colorcolumn() after copying window options.
Problem: Some source files are too big.
Solution: Move buffer and window related functions to evalbuffer.c and
evalwindow.c. (Yegappan Lakshmanan, closes#4898)
Problem: Using NULL pointer when out of memory.
Solution: Bail out or skip the code using the pointer. (Zu-Ming Jiang,
closes#4805, closes#4843, closes#4939, closes#4844)
Problem: Map functionality mixed with character input.
Solution: Move the map functionality to a separate file. (Yegappan
Lakshmanan, closes#4740) Graduate the +localmap feature.
Problem: Autocommand that splits window messes up window layout.
Solution: Disallow splitting a window while closing one. In ":all" give an
error when moving a window will not work.
Problem: ":write" increments b:changedtick even though nothing changed.
(Daniel Hahler)
Solution: Only increment b:changedtick if the modified flag is reset.
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: When evaluating 'statusline' the current window is unknown.
(Daniel Hahler)
Solution: Set "g:actual_curwin" for %{} items. Set "g:statusline_winid"
when evaluationg %!. (closes#4406, closes#3299)
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: When buffer is hidden "F" in 'shortmess' is not used.
Solution: Check the "F" flag in 'shortmess' when the buffer is already
loaded. (Jason Franklin) Add test_getvalue() to be able to test
this.
Problem: Asking about existing swap file unnecessarily.
Solution: When it is safe, delete the swap file. Remove
HAS_SWAP_EXISTS_ACTION, it is always defined. (closes#1237)
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: ml_get error when updating the status line and a terminal had its
scrollback cleared. (Chris Patuzzo)
Solution: Check the cursor position when drawing the status line.
(closes#3830)
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: Functionality for signs is spread out over several files.
Solution: Move most of the sign functionality into sign.c. (Yegappan
Lakshmanan, closes#3751)
