If it doesn't strip, but keeps adding ">", these additions will
accumulate.  Therefore, I think that it can only stop stripping if it
also stops adding ">".  And that cannot be don, AFAIU, if we want to
be able to preserve the mbox format (for example, the FCC feature in
Rmail saves messages in mbox files).

Am I missing something?
