Hey Micha,

I'm finally back to this problem.  I added your code
and it did something, but not what I'd hoped :) 
Initially both cases showed up as black which didn't
surprise me.  However I then changed 'gray10' in the
tab-face to 'red10' but still both spaces and tabs
were showing up as black squares.  My immediate
problem is solved as I ended up using hexl-mode which
isn't too user friendly but does allow me to
differentiate the two.  A quick question though:  How
could I discover what allowable values I could use
other than 'gray10?'  I'm pretty new to emacs.  I read
the doc for custom-set-faces but it left me confused. 
Thanks for taking the time to respond.
