Now that's just a difference of opinion. I think GDB should do the
smarter checking and CGDB should get the data. That way there are N
front ends that can assume the data that GDB is outputting is good.

As it stands now, the doco says that the fullname is absolute, and
therefor, CGDB expects that filename to be a unqiue key.
