That introduces a slight difference: in one case #:update-mtab? is not
honored.  That said, it’s probably OK to ignore it; maybe leave an “XXX”
comment above just in case.  ;-)

Otherwise LGTM.

Can you send a ‘git format-patch’ thing?  (Otherwise I could write the
commit log on your behalf.)

Thanks!
