git-rev-parse HEAD^1 would fail, because of an off-by-one bug (but HEAD^ would yield the expected result). Also, when the parent does not exist, do not silently return an incorrect SHA1. Of course, this no longer applies to git-rev-parse alone, but every user of get_sha1(). While at it, add a test.
