No, it wasn't documented whether the "Binary file matches" message is 
sent to stdout or to stderr. But now that you mention it, this should be 
documented. First patch attached, and installed into the development 
version.

Hmm, you have a point that -s is documented to "Suppress error messages 
about nonexistent or unreadable files" and it's plausible to say that 
the "binary file matches" diagnostic, although it is about a binary file 
that 'grep' has some trouble reading, is not about a file that is 
"unreadable". So, let's fix the code to match that part of the spec 
again. Second patch attached and installed.
