Re: "git stash" is not known to git

One has to use git-stash rather than "git stash".  Oversight?

Does any of the other shell-scripts work without dashes?
E.g. commit, merge, am, checkout?

If they do, then probably you are invoking older versions of
these scripts than what you think you are.  "git" itself looks
at GIT_EXEC_PATH and then the $(gitexecdir) from the Makefile
when it was built for its subcommands.

Perhaps this is your "symlinked install" gone awry?  I dunno.
