bug#21481: 24.5; show-paren-mode does not work with --color=no

[Simon Gerraty <sjg@juniper.net>]

Hi,

I've noticed in recent versions of Emacs that paren matching does not
work.

Turns out it *does* work, but I cannot see the result, because emacs is
started with --color=no (sorry but I cannot stand the color stuff)

If I start emacs without that paren matching works - using cyan
to highlight open paren.

That would suggest that the face used for show-paren-match is wrong -
ignoring color=no.

I cannot confirm that since I cannot seem to get any of the functions in
faces.el to run, even after explicitly loading it.
Which is odd.

I've seen this on multiple platforms, the common factor being emacs
