bug#6191: invert-face: different behaviour under POSIX and MS-Windows systems

[Eduard Wiebe]

 Hello,

i was to emulate "emacs*reverseVideo: true" under MS-Windows and rant
in some dark corners of `invert-face'.

Here my observations:

0. emacs -Q

1. M-x invert-face RET cursor RET

   MS-Windows: no effect

   FreeBSD:    no effect

   
2. M-x invert-face RET default RET

   MS-Windows: inverts only the background color, not the cursor face, which
               implies that cursor disappears in almost cases (buffer sections).

   FreeBSD:    inverts both


3. M-x invert-face RET cursor RET

   MS-Windows: invert cursor face as expected

   FreeBSD:    no effect


Tested under 23.1, 23.2 und the trunk version.
