bug#16619: 24.3.50; REGRESSION: transparent *Completions* now

[Drew Adams <drew.adams@oracle.com>]

This is with my setup, admittedly.  But it is a regression introduced
by vanilla Emacs: simply changing to this build from a build from a
week earlier (2014-01-23).

The effect: Now my *Completions* buffer is completely illegible
because it is transparent/weak/faded.  I even use a special-display
frame for *Completions*, for which I define the background as
"LavenderBlush2".  Nevertheless, the frame is transparent.
Everything about it is transparent: background, foreground, title bar,
everything.  This effect makes *Completions* completely useless and
unusable.

I tried to take a screenshot to show you what I see, but the
*Completions* frame does not even show up at all for the screenshot
software.  I.e., even though I can (barely) make out by eye that there
is a *Completions* frame there, when I create a screenshot covering
that area it does not show up at all in the screenshot.

I cannot use this build at all, unfortunately.

(I thought we were in a feature freeze.)
