From: Yegor Yefremov <yegorslists at googlemail.com>
Some packages don't provide source archive but only a wheel file. In
this case download variable is not defined. So define this variable at
the very beginning and check whether it is None after searching for
source archives in the metadata.
Bonus: fix PEP8 issue with wrong indentation.
