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

Indeed, that would solve the proble entirely. I wonder how this should
be implemented... Should the command store the rewriting rule, and have
find_and_open_source() use it when trying to locate source files?

Indeed, same file name used more than once in a project is an issue.
Perhaps the argument I was making saying that it "works" in most cases
is backwards, and it actually "works" in my coworker's case while it's
broken for most cases. I'm not sure I would thrilled at the prospect
of fixing this, knowing how delicate this can be.
