bug#5502: compile.el uses non-mode-line faces in the mode line

[karl@freefriends.org (Karl Berry)]

Hi Stefan,

    Why do you set inverse-video to nil?  

My real goal, as I mentioned, is to have inverse video in mode lines,
and all face attributes turned off in buffer contents in tty emacs.
(The behavior of Emacs for 20+ years, until Emacs 22 "improved" faces by
making them apply to tty windows, with no way to get the old behavior.
Sigh.)

I can give you more complex code if you want (ie, the code I'm actually
trying to use).  This minimal example was only intended to show that the
same compilation faces were being used in the mode line and buffer
contents, which other parts of Emacs do not do.

Thus, if I turn off faces for the buffer contents, they stay turned off
in the mode line, and vice versa.  If different faces were available,
they could be controlled independently.  (As an alternative, I suppose I
can try to defadvise mode line generation, or some such.)

    If you set it to `unspecified' instead, it should work right.

Unfortunately, it didn't help me do what I'm trying to do.

Thanks,
Karl
