Hi.  I recently installed octave-2.1.36, and found that emacs/otags is
unchanged from 2.0.14.  Here's a patch (diff -c) which will allow otags
to handle functions without arguments, as well as functions without
results.  I've been using it successfully for about a year.  A ChangeLog
entry is included at the end.  Questions to me.  /Jskud
