[PATCH 0/2] color: support "default" to restore fg/bg color

["Robert Estelle via GitGitGadget" <gitgitgadget@gmail.com>]

The name "default" can now be used in foreground or background colors, and
means to use the terminal's default color, discarding any explicitly-set
color without affecting the other attributes. On many modern terminals, this
is not the same as specifying "white" or "black".

Although attributes could previously be cleared like "no-bold", there had
not been a similar mechanism available for colors, other than a full
"reset", which cannot currently be combined with post-reset settings.

Note that this is not the same as the existing name "normal", which is a
no-op placeholder to permit setting the background without changing the
foreground. (i.e. what is currently called "normal" might have been more
descriptively named "inherit", "none", "pass" or similar).
