Problem: Nasty autocommand causes using freed memory. (Dominique Pelle)
Solution: Do not force executing autocommands if the value of 'syntax' or
'filetype' did not change.
Problem: Loading a session file fails if 'winheight' is a big number.
Solution: Set 'minwinheight' to zero at first. Don't give an error when
setting 'minwinheight' while 'winheight' is a big number.
Fix using vertical splits. Fix setting 'minwinwidth'.
(closes#2970)
Problem: Terminal window options are named inconsistently.
Solution: prefix terminal window options with "termwin". Keep the old names
for now as an alias.
Problem: Terminal windows in a session are not properly restored.
Solution: Add "terminal" in 'sessionoptions'. When possible restore the
command running in a terminal.
Problem: If $SHELL contains a space then the default value of 'shell' is
incorrect. (Matthew Horan)
Solution: Escape spaces in $SHELL. (Christian Brabandt, closes#459)
Problem: It is difficult to set the python home directory properly for
Python 2.7 and 3.5 since both use $PYTHONHOME.
Solution: Add the 'pythonhome' and 'pythonthreehome' options. (Kazuki
Sakamoto, closes#1266)
Problem: No error when settting 'renderoptions' to an invalid value before
starting the GUI.
Solution: Always check the value. (Ken Takata, closes#2413)
Problem: Options test fails when using Motif or GTK GUI.
Solution: Use "fixed" instead of "fixedsys" for Unix. Don't try "xxx" for
guifonteset. Don't set 'termencoding' to anything but "utf-8" for
GTK. Give an error if 'termencoding' can't be converted.
Problem: Cannot use imactivatefunc() unless compiled with +xim.
Solution: Allow using imactivatefunc() when not compiled with +xim.
(Yasuhiro Matsumoto, closes#2349)
Problem: balloon_show() only works in terminal when compiled with the GUI.
Solution: Add FEAT_BEVAL_GUI and refactor to move common code out of the GUI
specific file.
Problem: Cannot use 'balloonexpr' in a terminal.
Solution: Add 'balloonevalterm' and add code to handle mouse movements in a
terminal. Initial implementation for Unix with GUI.
Problem: ":set scroll&" often gives an error.
Solution: Don't use a fixed default value, use half the window height. Add a
test. (Ozaki Kiichi, closes#2104)
Problem: Mac features are confusing.
Solution: Make feature names more consistent, add "osxdarwin". Rename
feature flags, cleanup Mac code. (Kazunobu Kuriyama, closes#2178)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: $TERM names starting with "putty" and "cygwin" are likely to have
a dark background, but are not recognized.
Solution: Only check the first few characters of $TERM to match "putty" or
"cygwin". (Christian Brabandt)
Problem: Setting 'encoding' makes 'printheader' invalid.
Solution: Do not translate the default value of 'printheader'. (Yasuhiro
Matsumoto, closes#2026)
Problem: The cursor shape is not reset after it was changed in a terminal.
Solution: Request the original cursor shape and restore it. Add t_RS.
Do not add t_SH for now, it does not work properly.
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)
