I don't think it is necessary for us to have them all.  It is never an
error to use "warning off msgid", so it shouldn't matter whether we
actually have a warning with the given msgid.  But it would be nice if
we do the right thing for the warnings that we know about, and that
are common to both Octave and Matlab (divide by zero, for example).
And in those cases, it would also be nice to recognize the message ids
that Matlab uses, provided that doing so is not a lot of trouble.
