On X, on a tty, or both?

I don't have access to an X version where I type this, but on a tty,
invert-face works for me as advertized, at least for the `default'
face.  It works okay whether the fore- and background colors are
specified explicitly (as in "emacs -fg blue -bg black") or are left at
their default.

The MS-Windows port in its GUI version also DTRT.

Perhaps you could post a specific recipe to reproduce this?

Hmm... What about "unspecified-bg" etc.?

Anyway, I don't understand why is this needed, so my question might
not be relevant.
