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

[Jeff King]

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:

[Alex Riesen]

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.

Signed-off-by: Alex Riesen <raa.lkml@gmail.com>

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.

[PATCH] Fix "--pretty=format:" for parent related items.

[Junio C Hamano]

There are two breakages in the %P/%p interpolation.  It appended
an excess SP at the end of the list, and it gave uninitialized
contents of a buffer on the stack for root commits.

This fixes it, while updating the t6006 test which expected the
wrong output.
