[PATCH 3/7] grep: --count over binary

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

The intent of showing the message "Binary file xyz matches" for
binary files is to avoid annoying users by potentially messing up
their terminals by printing control characters.  In --count mode,
this precaution isn't necessary.

Display counts of matches if -c/--count was specified, even if -a
was not given.  GNU grep does the same.
