doc: fix comm's --help output so we generate a better man page

* src/comm.c (usage): Don't align example comments in --help output,
since the extra space (sequence of two spaces) there would be
interpreted by help2man and induce an unwanted line break
in the resulting man page.  Reported by Jari Aalto.
