It's best not to quit debugging and just recompile. That way you keep the
shell history as well as GDB's breakpoints, although some may have moved.

Then presumably you need to remember to turn it on again when you debug. I find
the tool bar useful for repetitive commands except that it doesn't work properly
with GTK. In this case, <RET> in the GUD buffer works well.

gdb-find-file-hook is an internal function not intended for general use.
It's role is too specialised for it's own hook variable.

Something like that should work but not for existing buffers which hold
source files.

Yes, it's only in the CVS repository.
