This doesn't instill confidence.  :)  Can we test this?

Also, I'm not sure I understand the comment, since you do call .scheme() in the
implementation.  What empty scheme are you referring to?

[wjmaclean, 2015/02/12 15:59:36]

Gah, just realized we're not changing anything! *Many* places just put in an
empty string for scheme, but ARH is one of the few that don't.

Nothing will break here.
