Comment:

 Looks good! I also ran `make check && make test-stem && make test-
 network`, and ran it through Travis where [https://travis-
 ci.org/isislovecruft/tor/builds/347530454 it passed].

 Stem was mad about some stuff, frequently erroring on `[] != ['']`, but
 I'm pretty sure that's a Stem problem? Or my Stem is too old or something
 (v1.4.1). Chutney seemed fine though.
