Currently writedelay shows the sequence of characters that are sent to
the UI/TUI module. Here nvim has already applied an optimization: when
attempting to put a char in a screen cell, if the same char already was
there with the same attributes, UI output is disabled. When debugging
redrawing it it sometimes more useful to inspect the redraw stream one
step earlier, what region of the screen nvim actually is recomputing
from buffer contents (win_line) and from evaluating statusline
expressions.
Take the popupmenu as an example. When closing the popupmenu (in the
TUI), currently 'writedelay' looks like vim only is redrawing the region
which the pum covered. This is not what happens internally: vim redraws
the entire screen, even if only outputs the changed region.
This commit allows negative values of 'writedelay', which causes a delay
for all redrawn characters, even if the character already was displayed
by the UI before.
Most fonts should have these by now. Both are a significant visual
improvement.
- Vertical connecting bar `│` is used by tmux, pstree, Windows 7 cmd.exe
and nvim-qt.exe.
- Middle dot `·` works on Windows 7 cmd.exe, nvim-qt.exe.
For reference: tmux uses these chars to draw lines: │ ├ ─
Per CMAKE docs, CMAKE_HOST_SYSTEM_VERSION is the result of `uname -r`:
https://cmake.org/cmake/help/v3.4/variable/CMAKE_HOST_SYSTEM_VERSION.html?highlight=uname
A numeric version string for the system. On systems that support
uname, this variable is set to the output of uname -r. On other
systems this is set to major-minor version numbers.
On Windows it is something like "6.1", so it won't match ".*-Microsoft".
Closes#7329
Problem: 'hlsearch' highlighting not removed after incsearch (lacygoill)
Solution: Redraw all windows. Start search at the end of the match. Improve
how CTRL-G works with incremental search. Add tests. (Christian
Brabandt, Hirohito Higashi, haya14busa, closesvim/vim#2267)

Until now, the default `:filetype ...` setup was skipped if the user
config touched `:filetype` in any way (including implicitly via `:syntax
on`). No one needs that, and it's very confusing.
Instead, proceed with `:filetype ... on` unless the user explicitly
called `:filetype ... off`.
closes#7765
TERM=konsole-256color is recognized by ncurses.
TERM=konsole-xterm might be more clever, but should not be necessary
(for Nvim at least), we already special-case Konsole in various places.
We may need to clean up some areas that currently assume Konsole always
"pretends xterm" (`TERM=xterm-256color`), though I didn't find any such
cases.

vim-patch:8.0.0320: warning for unused variable with small build
Use `@cond <something>` to obscure a section from doxygen.
doxygen thinks kvec_withinit_t() is a function. That adds noise to the
generated API documentation, and also prevents the following function
from being noticed.
Get terminal debugging info by starting Nvim with 'verbose' level 3:
nvim -V3log
This is like Vim's `:set termcap`, which was removed in Nvim (and would
be very awkward to restore because of the decoupled UI).
Since "builtin" terminfo definitions were implemented (7cbf52db1b),
the decisions made by tui.c and terminfo.c are more relevant. Exposing
that decision in the 'term' option helps with troubleshooting.
Also: remove code that allowed setting t_Co. `:set t_Co=…` has never
worked; the highlight_spec test asserting that nvim_set_option('t_Co')
_does_ work makes no sense, and should not have worked.
