Comment(by sjamaan):

 Replying to [comment:7 iraikov]:
 > I meant the discarding-of-empty-path-segments behavior. Some actual test
 cases that illustrate why this is a problem.

 Phew! Glad you agree :)

 > Now that I think about it, SMB file sharing URIs are also very insistent
 about keeping a large number of consecutive slashes, so I would not be
 surprised if the current uri-generic breaks those. And as I wrote this, I
 just realized that the uri-generic test cases do not include any SMB URIs,
 so we need to fix this, regardless of the outcome of this ticket.

 Could you come up with some particularly nasty examples? I have never
 really used SMB.
 I'm not sure having a lot of real-world examples matters that much, it's
 mostly the edge cases that are interesting for the tests. If we nail those
 down, the run-of-the-mill URIs will take care of themselves. But having a
 few example SMB uris would be good (just put them in the path-cases list.
 Be sure to update the comment too since these wouldn't be Python cases
 :P).

 > It does sound like keeping the empty path segments would be a sane
 behavior. Backward compatibility should not be a big issue, if any user of
 the library wanted to write their own normalization procedure that removes
 the empty segments, they can call update-uri and filter the path
 accordingly.

 Agreed!
