I just moved to a different continent to start a Ph.D, so I've been a
bit preoccupied.

Don't add minimum-X-extent to define-grobs.scm: the code in
align-interface.cc is subtle because of the pure-height calculations
(grobs can't suicide during pure-height calculations, so we need them to
remain empty, even if they have minimum-Y-extent; I'll have to cook up a
regression test that makes this obvious). I'll do a patch this weekend
or early next week if someone else doesn't get there first.

By the way, the whole problem would be avoided if it weren't for the
hacky treatment of minimum-Y-extent (we no longer space systems using
extents, but minimum-Y-extent gets special treatment for backwards
compatibility). But I think that's a problem for 2.13...
