Comment:

 This seems to be a combination of TravisCI's behavior on "branch builds":

 {{{
 git clone --depth=1000 --branch=towncrier-lint-failures
 https://github.com/LeastAuthority/tahoe-lafs.git
 }}}

 which results in a masterless checkout and towncrier's method of
 implementing its check feature:

 {{{
 ['git', 'diff', '--name-only', u'origin/master...']
 }}}

 The problem is somewhat exacerbated by the towncrier behavior of hiding
 the git output in this case.

 I'm going to call this not a bug in Tahoe-LAFS.  I've disabled "branch
 build" for LeastAuthority/tahoe-lafs (not even sure why it was on) and
 sent a PR to towncrier to improve error reporting
 (https://github.com/hawkowl/towncrier/pull/125).
