(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I've only skimmed this bug report, so I might well have missed
something.  Was there a conclusion here as to what should be done?  It
looks like useful functionality to me (but it's been years since I've
written tex-y stuff).

In any case, if this is to be applied, we'd need to have a copyright
assignment to the FSF on file.  David, would you be willing to sign
that?
