Gack! You mean they don't Just Work the way tabs do? That sounds totally
busted. Wouldn't they need to have sizes for hit-testing and
selection-drawing to work properly?
Even when you're not in Show Paragraphs mode, the user should still be able
to use the usual mouse or keyboard mechanisms to select a single "invisible"
run (which highlights just like a space or tab would) and then delete the
corresponding break.

Sigh. I'm still embarrassed that I never finished writing up the
description of how to implement fields as RTF-friendly containers. This
just makes it hurt more.
Kudos to Martin for coming up with a cool hack in the mean time, though.
