Should "dir" override the full path encoded in debug info?

substitute-path works for me too. (and I verified, no collision with
other commands).

Right now, the interface I have in mind is the following.

        (gdb) substitute-path from to

                Sets the substitution rule using "from" and "to".

        (gdb) substitute-path

                Delete the substitution rule

It just occured to me: Should add a way to show the current substitution
pattern? The "show" command prefix doesn't lend itself too well because
we have two arguments. Or perhaps is it ok to define our own processing
for the "show substitute-path" command:

        (gdb) show substitute-path
        Source paths are modified by substituting "from" with "to".

Thanks,
