Sure, but someone should bind default-directory.  Usually, when you
set a breakpoint from a buffer that visits a file, the natural thing
is to use that buffer's default-directory, so that's what GUD does.  I
think what Tom wants requires some way to tell GUD to do bind
default-directory, and also to tell it what directory to bind it to.

In other words, I think it's hard to expect that the existing code
could be tweaked on the user level into doing what Tom wants, but it's
not rocket science to change GUD to allow this mode.
