Protect get_author_ident_from_commit() from filenames in work tree
We used to use "cat-file commit $commit" to extract the original author information from existing commit, but an earlier commit 5ac2715 (Consistent message encoding while reusing log from an existing commit) changed it to use "git show -s $commit". If you have a file in your work tree that can be interpreted as a valid object name (e.g. "HEAD"), this conversion will not work. Disambiguate by marking the end of revision parameter on the comand line with an explicit "--" to fix this. This breakage is most visible with rebase when a file called "HEAD" exists in the worktree.
