(I'm going through old bug reports that unfortunately didn't get any
response at the time.)

Emacs now has the xref framework for this stuff, and it has
`xref-push-marker-stack', so I think this issue should now be solved,
and I'm closing this bug report.  If this is still something that should
be done, please reopen.
