closes#7698
Wrapping a command in double-quotes allows cmd.exe to safely dequote the
entire command as if the user entered the entire command in an
interactive prompt. This reduces the need to escape nested and uneven
double quotes.
The `/s` flag of cmd.exe makes the behaviour more reliable:
:set shellcmdflag=/s\ /c
Before this patch, cmd.exe cannot use cygwin echo.exe (as opposed to
cmd.exe `echo` builtin) even if it is wrapped in double quotes.
Example:
:: internal echo
> cmd /s /c " echo foo\:bar" "
foo\:bar"
:: cygwin echo.exe
> cmd /s /c " "echo" foo\:bar" "
foo:bar
Make HlAttr contain highlighting state for both color modes (cterm and rgb).
This allows us to implement termguicolors completely in the TUI.
Simplify some logic duplicated between ui.c and screen.c. Also avoid
some superfluous highlighting reset events.
The old behavior is probably not justified, for the usual reason:
terminal buffers may have interactive processes, so cursor placement is
arbitrary, therefore tracking it in the jumplist is useless (or worse).
N.B.: per the docstring for `checkpcmark()` it looks like we were
calling `checkpcmark()` and `setpcmark()` in the wrong order.

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.
This fixes an apparent difference in behavior between Lua and LuaJIT.
Lua fails to format nil:
test/functional/terminal/tui_spec.lua:381: bad argument #2 to 'format' (string expected, got nil)
To deal with SIGWINCH limitations on Windows, change some resize tests
to _shrink_ the screen width. ... But this didn't work, so still
ignoring those tests on Windows.
