Problem: Vim becomes unusable after opening new window in BufWritePre
event.
Solution: Call not_exiting(). (Martin Tournoij, closes#2205)
Also for "2q" when a help window is open. Add a test.
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: Manual folds are lost when a session file has the same buffer in
two windows. (Jeansen)
Solution: Use ":edit" only once. (Christian Brabandt, closes#1958)
Problem: Get "no write since last change" error in terminal window.
Solution: Use another message when closing a terminal window. Make ":quit!"
also end the job.
Problem: Options of a buffer for a terminal window are not set properly.
Solution: Add "terminal" value for 'buftype'. Make 'buftype' and
'bufhidden' not depend on the quickfix feature.
Also set the buffer name and show "running" or "finished" in the
window title.
Problem: Segfault with QuitPre autocommand closes the window. (Marek)
Solution: Check that the window pointer is still valid. (Christian Brabandt,
closes#1817)
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: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: The conf filetype detection is done before ftdetect scripts from
packages that are added later.
Solution: Add the FALLBACK argument to :setfiletype. (closes#1679,
closes#1693)
Problem: ml_get errors in silent Ex mode. (Dominique Pelle)
Solution: Clear valid flags when setting the cursor. Set the topline when
not in full screen mode.
Problem: Script for creating cmdidxs can be improved.
Solution: Count skipped lines instead of collecting the lines. Add "const".
(Dominique Pelle, closes#1594)
Problem: Looking up an Ex command is a bit slow.
Solution: Instead of just using the first letter, also use the second letter
to skip ahead in the list of commands. Generate the table with a
Perl script. (Dominique Pelle, closes#1589)
Problem: Tabs are not aligned when scrolling horizontally and a Tab doesn't
fit. (Axel Bender)
Solution: Handle a Tab as a not fitting character. (Christian Brabandt)
Also fix that ":redraw" does not scroll horizontally to show the
cursor. And fix the test that depended on the old behavior.
Problem: When creating a session when winminheight is 2 or larger and
loading that session gives an error.
Solution: Also set winminheight before setting winheight to 1. (Rafael
Bodill, neovim #5717)
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: When opening a buffer on a directory and inside a try/catch then
the BufEnter event is not triggered.
Solution: Return NOTDONE from readfile() for a directory and deal with the
three possible return values. (Justin M. Keyes, closes#1375,
closes#1353)
Problem: When the pattern of :filter does not have a separator then
completion of the command fails.
Solution: Skip over the pattern. (Ozaki Kiichi, clodes #1299)
