A minute after sending this I've realized that we need to apply the same
operations to S as well. In reply, I'm adding two more patches that
respectively:
1) perform normalization and translation in S by default (i.e. make it
match the default SRC_URI),
2) add a more convenient PYPI_NO_NORMALIZE variable that can be used to
control whether SRC_URI and S use normalized or legacy names.
