[PATCH] Add some basic tests of rev-list --pretty=format

From: Jeff King <hidden>
Date: 2016-06-15 22:43:01 

These could stand to be a little more complex, but it should
at least catch obvious problems (like the recently fixed %ct
bug).

Junio: warning, there is (intentional) trailing whitespace in one of the
test results.

Isn't this a bit wrong for initial commit?

[PATCH] Improve output of %p and %P format in git-rev-list --pretty=format:

From: Alex Riesen <hidden>
Date: 2016-06-15 22:43:02 

Remove the terminating space from the space-separated list of parents.
Also fix the test t6006: it wrongly assumed that the initial commit
has a parent and was not executable.

The test even hardcoded parents of the initial commit to the
initial commit itself, which does not make any sense at all.

Argh, yes. As is probably obvious, I moved the actual output to be
'expected' after giving it a cursory check, but I was more focused on
the author/committer information, since that's where I was fixing bugs.
Good catch.

This is obviously fairly untested code.  I will follow up with a few
more tests for encoding/body to help make it more complete.
