Problem: winpty.dll name is fixed.
Solution: Add the 'winptydll' option. Make the default name depend on
whether it is a 32-bit or 64-bit build. (idea by Yasuhiro
Matsumoto, closes#1978)
Problem: Not easy to start Vim cleanly without changing the viminfo file.
Not possible to know whether the -i command line flag was used.
Solution: Add the --clean command line argument. Add the 'viminfofile'
option. Add "-u DEFAULTS".
Problem: No terminal emulator support. Cannot properly run commands in the
GUI. Cannot run a job interactively with an ssh connection.
Solution: Very early implementation of the :terminal command. Includes
libvterm converted to ANSI C. Many parts still missing.
Problem: It is not so easy to write a script that works with both Python 2
and Python 3, even when the Python code works with both.
Solution: Add 'pyxversion', :pyx, etc. (Marc Weber, Ken Takata)
Problem: 'formatprg' is a global option but the value may depend on the
type of buffer. (Sung Pae)
Solution: Make 'formatprg' global-local. (closes#1380)
Problem: The 'langnoremap' option leads to double negatives. And it does
not work for the last character of a mapping.
Solution: Add 'langremap' with the opposite value. Keep 'langnoremap' for
backwards compatibility. Make it work for the last character of a
mapping. Make the test work.
Problem: There is no equivalent of 'smartcase' for a tag search.
Solution: Add value "followscs" and "smart" to 'tagcase'. (Christian
Brabandt, closes#712) Turn tagcase test into new style.
Problem: Setting 'display' to "lastline" is a drastic change, while
omitting it results in lots of "@" lines.
Solution: Add "truncate" to show "@@@" for a truncated line.
Problem: The versplit feature makes the code uneccessary complicated.
Solution: Remove FEAT_VERTSPLIT, always support vertical splits when
FEAT_WINDOWS is defined.
Problem: Although emoji characters are ambiguous width, best is to treat
them as full width.
Solution: Update the Unicode character tables. Add the 'emoji' options.
(Yasuhiro Matsumoto)
Problem: User may yank or put using the register being recorded in.
Solution: Add the recording register in the message. (Christian Brabandt,
closes#470)
Problem: Libraries for dynamically loading interfaces can only be defined
at compile time.
Solution: Add options to specify the dll names. (Kazuki Sakamoto,
closes#452)
Problem: On some systems automatically adding the missing EOL causes
problems. Setting 'binary' has too many side effects.
Solution: Add the 'fixeol' option, default on. (Pavel Samarkin)
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: 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: Still have old hacking code for Input Method.
Solution: Add 'imactivatefunc' and 'imstatusfunc' as a generic solution to
Input Method activation. (Yukihiro Nakadaira)
Problem: Syntax highlighting can be slow.
Solution: Include the NFA regexp engine. Add the 'regexpengine' option to
select which one is used. (various authors, including Ken Takata,
Andrei Aiordachioaie, Russ Cox, Xiaozhou Liua, Ian Young)
Problem: On some systems case of file names is always ignored, on others
never.
Solution: Add the 'fileignorecase' option to control this at runtime.
Implies 'wildignorecase'.
