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: In a terminal 'ballooneval' does not work right away.
Solution: Flush output after drawing the balloon. Add the <Ignore> key
code. Add a test.
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: Vim script debugger functionality needs cleanup.
Solution: Move debugger code to a separate file. Add more tests. (Yegappan
Lakshmanan, closes#4285)
Problem: Not all Vim variables require the v: prefix.
Solution: When scriptversion is 3 all Vim variables can only be used with
the v: prefix. (Ken Takata, closes#4274)
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: 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: It is not easy to edit a script that was sourced.
Solution: Add a count to ":scriptnames", so that ":script 40" edits the
script with script ID 40.
Problem: Cannot get the script line number when executing a function.
Solution: Store the line number besides the script ID. (Ozaki Kiichi,
closes#3362) Also display the line number with ":verbose set".
Problem: An "after" directory of a package is appended to 'rtp', which
will be after the user's "after" directory. ()
Solution: Insert the package "after" directory before any other "after"
directory in 'rtp'. (closes#3409)
Problem: :argadd in empty buffer changes the buffer name. (Pavol Juhas)
Solution: Don't re-use the current buffer when not going to edit the file.
(closes#3397) Do re-use the current buffer for :next.
Problem: 'autowrite' takes effect when buffer is not to be written.
Solution: Don't write buffers that are not supposed to be written. (Even Q
Jones, closes#3391) Add tests for 'autowrite'.
Problem: A timer may change v:count unexpectedly.
Solution: Save and restore v:count and similar variables when a timer
callback is invoked. (closes#2897)
Problem: Buffer of a terminal only updated in Terminal-Normal mode.
Solution: Copy the terminal window content to the buffer when in
Terminal-Job mode.
Problem: :argedit does not reuse an empty unnamed buffer.
Solution: Add the BLN_CURBUF flag and fix all the side effects. (Christian
Brabandt, closes#2713)
Problem: Package directory not added to 'rtp' if prefix matches.
Solution: Check the match is a full match. (Ozaki Kiichi, closes#2817)
Also handle different ways of spelling a path.
