Subject: [PATCH 03/11] t/t3511: add some tests of 'cherry-pick -s' functionality

From: Brandon Casey <[email-masked]>
Date: Sun, 25 Nov 2012 17:45:51 -0800

Add some tests to ensure that 'cherry-pick -s' operates in the following
manner:

   * Inserts a blank line before appending a s-o-b to a commit message that
     does not contain a s-o-b footer

   * Does not mistake first line "subject: description" as a s-o-b footer

   * Does not mistake single word message body as conforming to rfc2822

   * Appends a s-o-b when last s-o-b in footer does not match committer
     s-o-b, even when committer's s-o-b exists elsewhere in footer.

   * Does not append a s-o-b when last s-o-b matches committer s-o-b

   * Correctly detects a non-conforming footer containing a mix of s-o-b
     like elements and s-o-b elements. (marked "expect failure")
