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: An error in a timer can make Vim unusable.
Solution: Don't set the error flag or exception from a timer. Stop a timer
if it causes an error 3 out of 3 times. Discard an exception
caused inside a timer.
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: Minor issues related to quickfix.
Solution: Set the proper return status for all cases in setqflist() and at
test cases for this. Move the "adding" flag outside of
FEAT_WINDOWS. Minor update to the setqflist() help text. (Yegappan
Lakshmanan)
Problem: Crash when closing the quickfix window in a FileType autocommand
that triggers when the quickfix window is opened.
Solution: Save the new value before triggering the OptionSet autocommand.
Add the "starting" flag to test_override() to make the text work.
Problem: Text found after :endfunction is silently ignored.
Solution: Give a warning if 'verbose' is set. When | or \n are used,
execute the text as a command.
Problem: Cannot easily get to the last quickfix list.
Solution: Add "$" as a value for the "nr" argument of getqflist() and
setqflist(). (Yegappan Lakshmanan)
Problem: The :global command does not work recursively, which makes it
difficult to execute a command on a line where one pattern matches
and another does not match. (Miles Cranmer)
Solution: Allow for recursion if it is for only one line. (closes#1760)
Problem: Character classes are not well tested. They can differ between
platforms.
Solution: Add tests. In the documentation make clear which classes depend
on what library function. Only use :cntrl: and :graph: for ASCII.
(Kazunobu Kuriyama, Dominique Pelle, closes#1560)
Update the documentation.
Problem: On MS-Windows ":!start" does not work as expected.
Solution: When creating a process fails try passing the argument to
ShellExecute(). (Katsuya Hino, closes#1570)
Problem: Not enough testing for the client-server feature.
Solution: Add more tests. Add the remote_startserver() function. Fix that
a locally evaluated expression uses function-local variables.
Problem: The return value of mode() does not indicate that completion is
active in Replace and Insert mode. (Zhen-Huan (Kenny) Hu)
Solution: Add "c" or "x" for two kinds of completion. (Yegappan Lakshmanan,
closes#1397) Test some more modes.
Problem: When calling setpos() with a buffer argument it often is ignored.
(Matthew Malcomson)
Solution: Make the buffer argument work for all marks local to a buffer.
(neovim #5713) Add more tests.
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)
