That's not a persuasive example, as

# grep root /etc/passwd *.html

does what you want and is obviously cleaner than the --fake-filename
approach.  I guess I'd have to see a real example to see what people
are driving at.

Hmm, that wasn't clear to me, and still isn't.  Sorry, I guess I'm not
getting the motivation.

How about if we change grep to output "-:" instead of "(standard
input):"?  That might address some of the issue here.  It would be
less ambiguous, and it would easier to program with in i18n
