Hmm, align_atom_parser() has already been called before we get here,
right? And it has already invoked match_atom_name() and died if the
argument to "align:" was missing, correct? If so, then this invocation
of match_atom_name() in populate_value() is unnecessary and should be
replaced with a simpler starts_with("align:").
Plus, 'valp' is not used, aside from this unnecessary
match_atom_name(), thus it can be removed as well.
