Actually, I think that $default_value is the only other serious enough
candidate that we should support, and I think we should support it both
from the directory and module_pathname parameters.

Also, it seems to me that while the $directory macro should still be
found only at the beginning of the module_pathname value, the
$default_value should be substituted from wherever it is found.

Please find attached a v1 version of the patch implementing that.
