Comment (by asn):

 Please see branch `bug25870` in my github repo which does some doc
 clarifications (which I hope you agree with), and  also introduces a
 unittest that does some basic tests on vanguard path selection.

 The unittest doesn't actually test many aspects of this ticket (apart from
 the fact that vanguard circuits need to be longer than 4 hops), but
 extending it to check the lifting of path restrictions is not so hard.
 Perhaps I can open a ticket about this and do it before the closing of 034
 but after merging this ticket.
