bug#24450: pypi importer outputs strange character series in optional dependency case.

[ng0 <ng0@we.make.ritual.n0.is>]

Hi Maxim,

great to see this fixed. Weird it bumped into my view after
almost 3 years. I trust that other people will have tested
it, I'm all over the place and mostly doing NetBSD and GNUnet
now.
Sorry if I have written a reply before, the thread was
marked as unread here.
