patch

I hit a crash printing in a debug build due to font inflation code.  This crash would also affect builds with font inflation enabled and affect other sorts of pagination (e.g., multicol).  (There's some font inflation code that I intentionally run in debug builds even when font inflation is disabled, so that we see the assertions.)

In any case, this patch fixes it; it's one place I missed maintaining the invariant that this function operates only on first-in-flows.

Crashed again; turns out I missed another one.  Hopefully this is really the last one, though.
