Problem: Using a range for window and buffer commands has a few problems.
Cannot specify the type of range for a user command.
Solution: Add the -addr argument for user commands. Fix problems. (Marcin
Szamotulski)
Problem: Crash when computing buffer count. Problem with range for user
commands. Line range wrong in Visual area.
Solution: Avoid segfault in compute_buffer_local_count(). Check for
CMD_USER when checking type of range. (Marcin Szamotulski)
Problem: Value of v:hlsearch reflects an internal variable.
Solution: Make the value reflect whether search highlighting is actually
displayed. (Christian Brabandt)
Problem: Many commands take a count or range that is not using line
numbers.
Solution: For each command specify what kind of count it uses. For windows,
buffers and arguments have "$" and "." have a relevant meaning.
(Marcin Szamotulski)
Problem: Language mapping also applies to mapped characters.
Solution: Add the 'langnoremap' option, when on 'langmap' does not apply to
mapped characters. (Christian Brabandt)
Problem: With some regexp patterns the NFA engine uses many states and
becomes very slow. To the user it looks like Vim freezes.
Solution: When the number of states reaches a limit fall back to the old
engine. (Christian Brabandt)
Problem: Not all commands that edit another buffer support the +cmd
argument.
Solution: Add the +cmd argument to relevant commands. (Marcin Szamotulski)
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: 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)
