Problem: Wildcards are not expanded for :terminal.
Solution: Add FILES to the command flags. (Yasuhiro Matsumoto, closesvim/vim#1883)
Also complete commands.

Problem: reg_executing() is reset by calling input().
Solution: Implement a more generic way to save and restore reg_executing.

Problem: Functionality for signs is spread out over several files.
Solution: Move most of the sign functionality into sign.c. (Yegappan

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.

Lua port of create_cmdidxs.vim from 8.0.0572
N/A:
vim-patch:8.0.0572: building the command table requires Perl
Problem: Building the command table requires Perl.
Solution: Use a Vim script solution. (Dominique Pelle, closesvim/vim#1641)

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, closesvim/vim#1589)

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.

wp->w_height_inner now contains the "inner" size, regardless if the
window has been drawn yet or not. It should be used instead of
wp->w_grid.Rows, for stuff that is not directly related to accessing
the allocated grid memory, such like cursor movement and terminal size
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)

Avoid clearing the screen in most situations. NOT_VALID should be
equivalent to CLEAR unless some external force messed up the terminal,
for these situations <c-l> and :mode will still clear the screen.
Also eliminate some obsolete code in screen.c, that dealt with that in
vim drawing window 1 can mess up window 2, but this never happens in
nvim.
But what about slow terminals? There is two common meanings in which
a terminal is said to be "slow":
Most commonly (and in the sense of vim:s nottyfast) it means low
bandwidth for sending bytes from nvim to the terminal. If the screen is
very similar before and after the update_screen(CLEAR) this change
should reduce bandwidth. If the screen is quite different, but there is
no new regions of contiguous whitespace, clearing doesn't reduce
bandwidth significantly. If the new screen contains a lot of whitespace,
it will depend of if vsplits are used or not: as long as there is no
vsplits, ce is used to cheaply clear the rest of the line, so
full-screen clear is not needed to reduce bandwith. However a left
vsplit currently needs to be padded with whitespace all the way to the
separator. It is possible ec (clear N chars) can be used to reduce
bandwidth here if this is a problem. (All of this assumes that one
doesn't set Normal guibg=... on a non-BCE terminal, if you do you are
doomed regardless of this change).
Slow can also mean that drawing pixels on the screen is slow. E-ink
screens is a recent example. Avoiding clearing and redrawing the
unchanged part of the screen will always improve performance in these
cases.
clang scan-build noticed that find_command() may bitmask `eap->flags`.
cmd_can_preview() only uses `ea.cmdidx`, but let's fix the warning...

Problem: Weird autocmd may cause arglist to be changed recursively.
Solution: Prevent recursively changing the argument list. (Christian
Brabandt, closesvim/vim#2472)

Vim :! may "mess up the screen" because of e.g. switching between cooked
mode, but Nvim just uses pipes. So maybe we can avoid these
redraw_later_clear() CYA calls.
