The problem is that a single culprit could not be identified. Ideally the bisect would print out the range.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/tools/build.git/+/a7cdbdfb1d955f04974fe47c2b4e20fe91f5b3ee

commit a7cdbdfb1d955f04974fe47c2b4e20fe91f5b3ee
Author: Roberto Carrillo <robertocn@google.com>
Date: Mon Dec 05 22:35:47 2016

Correct inconclusive bisect messaging.

This re-does https://chromium-review.googlesource.com/#/c/411502/ and
addresses the comments by clarifying the flow of the conditions.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/tools/build.git/+/7c86ca265e7d1040175bd012afd6ef6492803ef1

commit 7c86ca265e7d1040175bd012afd6ef6492803ef1
Author: Roberto Carrillo <robertocn@google.com>
Date: Thu Dec 08 18:33:54 2016

Fixing layout of abort reason, removing line breaks from exception.

The details of why a bisect was inconclusive (such as a range of
revisions failing to build) are both the abort reason to be specified
in the bisect report, and the details of the bisect failure. However,
for failing a bisect, we need a string with no newlines as a message
for the StepFailure exception, while for readability we need them in
the bisect report. This change removes the newlines from the message
before raising the failure.

Current plan is to pack the json with relevant data and let the dashboard sort the message out instead of this hybrid approach where part of the message is generated in the recipe and the rest is done when we update the bug.
