Merge branch 'tb/connect-ipv6-parse-fix' into maint

An earlier update to the parser that disects a URL broke an
address, followed by a colon, followed by an empty string (instead
of the port number), e.g. ssh://example.com:/path/to/repo.

* tb/connect-ipv6-parse-fix:
  connect.c: ignore extra colon after hostname
