Great -- never sure if my intuitive use corresponds with that of others.

Good point, and shouldn't be too hard to fix. It seems like it could be
done either (a) at the lisp level (filtering out the blank entries), or
(b) at the literal buffer level (having a step that sets point-max for
the region appropriately). The choice (a) seems clearer in an abstract
way, but has the downside of needing to be repeated twice (both for
database tagging, and for rewriting the tags on the screen). I'll play
with both and see which is clearer.
