Hi. The patch fixes 17676. 19901 is a slightly different problem, and
the attached patch fixes that as well.

I'm not concerned about gdb-mi here; just the old-style gud. I've seen
the new display-buffer behavior similarly affect the behavior of some
other things, like xcscope.el for instance (I'll handle that once this
change is OKed). I feel like the attached patch is the default behavior
I want most of the time, but this is probably different for each user.

Thanks
