Subject: [BUG] b9c8e7f2fb6e breaks git bisect visualize
Message-ID: <20170614000630.44uctc5y7dyyleqy@sunbase.org>

Commit b9c8e7f2fb6e ("prefix_ref_iterator: don't trim too much") breaks 
git bisect visualize, this reproduces the bug:

  $ git bisect start
  $ git bisect bad
  $ git bisect good HEAD^^
  $ git bisect visualize
  fatal: BUG: attempt to trim too many characters
  $

Reverting b9c8e7f2fb6e makes git bisect visualize work again.

Tested on Debian GNU/Linux 8.8 (jessie).
