[PATCH] status: default in-progress color to header color

[Jeff King <peff@peff.net>]

The "status" command recently learned to describe the
in-progress operation in its long output format (e.g.,
rebasing, am, etc). The color for this message defaults to
"normal" (i.e., no color). However, if the user has set
their default header color to something besides normal, then
the message sticks out. A much saner default is to pick the
user's header color, making this message match the rest of
the header.

We already do the same trick with the "onbranch" message.
Rather than expand the current conditional to list all types
of messages which will default back to the header color, we
can just default all "nil" colors to do so, simplifying the
code. That encompasses all of the current nil color slots,
and will likely cover any future ones that will be added.

This goes on top of lk/more-helpful-status-hints.

My intent was that this would also let "color.status.inprogress"
override it, in case a user really wanted a green message or something.
However, I notice that the original series did not add such a config
option, so this color cannot be configured at all. Furthermore, I think
the color formatting for this message is somewhat buggy.  Even if we set
it to green, you would end up with (imagine our header color is blue):

  <blue># On branch master<reset>
  <green># You are in the middle of a rebase.<reset>

when what you would probably want is:

  <blue># On branch master<reset>
  <blue># <reset><green>You are in the middle of a rebase.<reset>

I.e., the "#" bit should always be in the header color, and only the
message text should change colors. This is how the "onbranch" message is
handled.

But given that this is not even configurable in the current code, I
really wonder if it needs to have its own color at all. Do people really
want to set the color of this message separately? Maybe we should just
use WT_STATUS_HEADER instead.
