When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now.
