That is what I do too.  Note that ":" is command and everything
afterward is an option argument to it.  Therefore proper quoting must
be applied.  Therefore I always quote the rest of the line as one
argument.

  : debug: "Doing this because a < b & * is better than ?"

Trying to use shell metacharacters in comments without quoting would
of course cause trouble.  But quoted they are fine.
