The sample hook to prepare the commit message before a commit allows users to opt-in to add the signature to the commit message. The signature is added at a place that isn't consistent with the "-s" option of "git commit". Further, it could go out of view in certain cases.
Add the signature in a way similar to "-s" option of "git commit" using git's interpret-trailers command. It works well in all cases except when the user invokes "git commit" without any arguments. In that case manually add a new line after the first line to ensure it's consistent with the output of "-s" option. While at it, name the input parameters to improve readability of script.
