When running git-stash on an empty repository, don't let the underlying
error messages leak through to the surface; instead, redirect them to
/dev/null.

Sign-off?

Is create_stash (hence save_stash) the only operation that do not make sense when HEAD is not born yet? I am wondering if it makes more sense to either:

 (1) catch the case where HEAD is not born yet a lot earlier and do not
     let the control even reach these functions (i.e. die inside the
     case/esac statement at the end of the script); or
 (2) pretend as if HEAD is a commit that records an empty tree, and not
     error out to begin with.

If either one of the above turns out to make sense, then the issue this patch addresses becomes irrelevant, so...

Oops, I'm not really used to the whole sign-off thing.

I think it would be more consistent if stash worked without any commits having taken place so I'll look at (2).
