So you're saying:
- if the PC is in this function, only stop when this frame reaches it.
- if the PC is the _beginning_ of a function (what about prologue
skipping, does that come into this? I don't remember if
decode_line_1 will skip the prologue, but I think it will.) or in
some other function, stop in any frame.

I'd be happier if those two behaviors had different names, but the
logical name I'd give to both of them is "until", so I guess we'll just
have to live with this. (3) is meaningful when inside the function
too, and with this scheme there's no way to express that without using
breakpoints; but I think that's a small loss.
