Yes, in the test pair both files lack a newline.  However, that
doesn't make a difference here: when I add a newline it still fails.

This is exactly what I do, and it fails for me every time with the
above mode-line face customization.

I would be mystified if no one else gets this behavior; I don't have
unusual hardware (a four-year old Samsung laptop with a Pentium III
CPU and a Savage IX/MV graphics card) or software (SUSE 9.0 with Linux
2.4.21).  Is the version of Emacs you tried my test with compiled with
GTK+?  I suspect the problem may lie there, since as I mentioned it
doesn't happen with CVS ntemacs under Windows XP, nor with the Emacs
that comes with SUSE 9.0, 21.3 compiled with the Athena toolkit.  (If
it were really necessary I could compile my CVS Emacs with the Athena
toolkit to see if I still get the failure, but I'd prefer it if
someone else could reproduce it.)
