> Or is this a "we'll get it next time"?
It's a "we'll get it next time." But really, it won't work, since if we
get a descriptor with the right digest, then -- barring sha1 collisions --
we'll get the same descriptor we already had: the one with the wrong
identity key.
Another option might be to mark the descriptor as "just don't download
this." Possibly that's a better idea.
> Is there a reason to pass seen_descriptor_digests as a parameter?
It needs to stay around between invocations of
routerstatus_parse_entry_from_string, since each call to
routerstatus_parse_entry_from_string will parse only a single entry, but
we want to check (as we parse each entry) whether we have seen *any*
duplicate entries before.
