I do now. It didn't even occur to me that this would change between
6.3 and CVS. I'll assume that was a deliberate change... is this going
to bust frontends?

Let's not wait on that. You've demonstrated a use for
-stack-info-frame relative to the current source base. That's plenty
good enough for me.
Of course now we need to re-add the documentation (with example this
time). A test case would be nice too. Since we've decided that we do
want this feature, could you put that together?
I'm going to be travelling all next week, but I should have time to
review the occasional patch anyway.
