  Normally the function @code{define-abbrev} sets the variable
! @code{abbrevs-changed} to @code{t}.  But if @var{system-flag} is
! address@hidden, that says the abbrev is a ``system'' abbrev.  In that
! case, @code{define-abbrev} does not alter @code{abbrevs-changed}.
! Instead it marks the abbrev as a ``system'' abbrev with the
! @code{system-type} property.

! does not do this for a ``system'' abbrev, since those won't be saved
