Ah, so these are one-off flags, and not indications of the resize,
i.e. they are not supposed to be sensitive to, say, when a tool bar
becomes too large for one line and needs two, is that so?

No, I think the cause of the problem is that we have no equivalent of
"C-x 6 f" that turns on the tool bar as a side effect of a command
that displays a buffer.  But that's a guess, because I've just
established with Jimmy's help that even the call to redraw_frame
doesn't cause the expected effect.  Which completely stumps me, and I
need to think about it before I come with more ideas (_if_ I come with
more ideas)...
