grepc: Usage: ffix

Using caps instead of <> will be nicer when we add options and
optional arguments for the files/directories:

  Usage: grepc [OPTION]... IDENTIFIER [FILE]...

vs

  Usage: grepc [<option>]... IDENTIFIER [<file>]...

Also, it's what pcregrep(1) and GNU grep(1) use, so it's good to
use the same syntax here.
