Split a new function roff_parse_comment() out of roff_expand() because this

functionality is not needed when called from roff_getarg().  This makes the
long and complicated function roff_expand() significantly shorter, and also
simpler in so far as it no longer needs to return ROFF_APPEND.
No functional change intended.
