No, after the "fix" lines got broken after $...$ even when $...$ fitted
perfectly well onto the line.

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.

I'm pretty sure about that.  I'm currently in a bind regarding tax
deadlines so I cannot really start investigating.  But I'm pretty sure
that something in either Emacs or AUCTeX must have significantly
changed.
