This sounds like the obvious point to insert the reminder that zero-length
runs are a hack we'd probably be better off without. How many different
types of these do we have now?
I'm already on record that we need non-zero-length runs at EOB (so that we
can get selection behaviors right there, not to mention the glaring lack of
those funky Show Paragraph symbols.)

I know Jeff was never thrilled with the behavior of FmtMarks either, but
until someone comes up with a better mechanism, that one should probably
stay.
Other than those two cases, do we have any other zero-length runs? The code
could certainly get a lot simpler in places if we didn't constantly have to
work around them.
