Comment 5 for bug 1518106

Sourcing in the "export_modules_dir.sh" script causes $0 to be "bash" in gnome-terminal and "/bin/bash" in terminator. When executing the script $0 is ./export_modules_dir.sh as one would expect.

Since the script is being sourced in I don't think it dirname should be used.
