Joel,

My opinion is that this is a reasonable change providing that we
still have a mechanism for setting a breakpoint on the prologue.
When I want to do this I usually do ``b *foo'' instead of relying
on line numbers.  (Usually I don't know the line number anyway.)
So, I have no objection to this patch so long as it doesn't change
the present behavior of ``b *foo''.

I've reread the thread in which this matter was discussed earlier
(i.e, the "[RFC] breakpoints and function prologues" messages).  Given
that there was such disagreement before, I doubt that everyone will
agree with my point of view.  If this turns out to be the case, might
I suggest a user settable option for controlling whether setting a
breakpoint by line number will always cause the prologue to be
skipped?  That way both sides get the behavior they want.  (GUIs can
set the desired behavior at initialization time.)
