I'm pretty sure that the functionality worked fine a few years ago since
I had been using it extensively then (I've not been doing as much
recently).  So there must have been changes in between for the worse.

deadlines so I cannot really start investigating.  But I'm pretty sure
that something in either Emacs or AUCTeX must have significantly
