Unless I misunderstand something, shouldn't grog detect e.g. a
.cstart macro in a document and then come up with a suggestion
that includes the "-j" argument for the chem(1) preprocessor?


  ~/ % echo .cstart | ./grog.pl
  groff -


These do not work either:


  'lilypond', 'glilypond',
  'Perl',     'gperl',
  'pinyin',   'gpinyin',


This is both with the git version of groff and with 1.23.0
