Alternate refs backends might store reflogs somewhere other than .git/logs. Change most test code that directly accesses .git/logs to instead use git reflog commands. There are still a few tests which need direct access to reflogs: to check reflog permissions, to manually create reflogs from scratch, to save/restore reflogs, to check the format of raw reflog data, and to remove not just reflog contents, but the reflogs themselves. All cases which don't need direct access have been modified. Signed-off-by: David Turner <dturner@twopensource.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

test_description='
|
|
Test pruning of repositories with minor corruptions. The goal
|
|
here is that we should always be erring on the side of safety. So
|
|
if we see, for example, a ref with a bogus name, it is OK either to
|
|
bail out or to proceed using it as a reachable tip, but it is _not_
|
|
OK to proceed as if it did not exist. Otherwise we might silently
|
|
delete objects that cannot be recovered.
