Suggestion for gdb-ui.el

The code was meant to do this but didn't because of an issue with point
and window point.  If you update from the repository this should work now.

This shouldn't be too hard to do with the GDB/MI commands.  I have other
changes that also use GDB/MI but I am waiting till after the release before
installing them in case such changes introduce bugs.  How useful is this
feature? I've not done low-level debugging or watched the contents of the
registers.  What debugging situations require this?  Are you debugging a
disassembly view in GDB from C code, or assembler (either generated by the
compiler or hand written) directly.

I've not seen this with Mandrake 9.0. It might be because I've been fiddling
with the code that displays disassembly.  Perhaps Jan Djarv knows if it's a
GTK problem.
