Ensure all flags have a short variant

macOS/BSD getopt does not allow for long flag variants without
installing gnu-getopt. This makes it hard to bundle git-flow with
applications, since you usually can't bundle gnu-getopt with them.
To address this, a short variant has been added for each command.
