Problem: gettabvar() is not consistent with getwinvar() and getbufvar().
Solution: Return a dict with all variables when the varname is empty.
(Yasuhiro Matsumoto)
Problem: When an InsertCharPre autocommand executes system() typeahead may
be echoed and messes up the display. (Jacob Niehus)
Solution: Do not set cooked mode when invoked from ":silent".
Problem: Encryption implementation is messy. Blowfish encryption has a
weakness.
Solution: Refactor the encryption, store the state in an allocated struct
instead of using a save/restore mechanism. Introduce the
"blowfish2" method, which does not have the weakness and encrypts
the whole undo file. (largely by David Leadbeater)
Problem: Matchparen only uses the topmost syntax item.
Solution: Go through the syntax stack to find items. (James McCoy)
Also use getcurpos() when possible.
Problem: Text drawing on newer MS-Windows systems is suboptimal. Some
multi-byte characters are not displayed, even though the same font
in Notepad can display them. (Srinath Avadhanula)
Solution: Add the 'renderoptions' option to enable Direct-X drawing. (Taro
Muraoka)
Problem: Cannot wrap lines taking indent into account.
Solution: Add the 'breakindent' option. (many authors, final improvements by
Christian Brabandt)
Problem: Using a regexp pattern to highlight a specific position can be
slow.
Solution: Add matchaddpos() to highlight specific positions efficiently.
(Alexey Radkov)
Problem: globpath() returns a string, making it difficult to get a list of
matches. (Greg Novack)
Solution: Add an optional argument like with glob(). (Adnan Zafar)
Problem: When passing input to system() there is no way to keep NUL and
NL characters separate.
Solution: Optionally use a list for the system() input. (ZyX)
Problem: getreg() does not distinguish between a NL used for a line break
and a NL used for a NUL character.
Solution: Add another argument to return a list. (ZyX)
Problem: The string returned by submatch() does not distinguish between a
NL from a line break and a NL that stands for a NUL character.
Solution: Add a second argument to return a list. (ZyX)
Problem: Inconsistency: ":sp foo" does not reload "foo", unless "foo" is
the current buffer. (Liang Li)
Solution: Do not reload the current buffer on a split command.
