I see.  I should have realized that before...

Hmm.  Why not simply "^[^>]+>+ "?

Anyway, setting PS1 inside .octaverc is useless with run-octave, because
PS1 is then reset to "octave> ".  Mh.  inferior-octave-startup does it.
Why?

In principle, the inferior octave mode could detect this and adjust
comint-prompt-regexp accordingly.  Or just ignore this problem (as it
currently does).
