t4150: tests for am --[no-]scissors

pyokagan · gitster · commit bf72ac17d7c9 · 2015-07-20T10:52:43.000-07:00
Since 017678b (am/mailinfo: Disable scissors processing by default,
2009-08-26), git-am supported the --[no-]scissors option, passing it to
git-mailinfo.

Add tests to ensure that git-am will pass the --scissors option to
git-mailinfo, and that --no-scissors will override the configuration
setting of mailinfo.scissors.
