Perhaps we would want to replay the stash always with --index for this
application.  By definition this will be conflict-free both in the index
and in the working tree.

I've also toyed with an idea to make <branchname> optional, and detach the
HEAD if <branchname> is not given.  It would be a useful mode of operation
but one problem is that it is _not_ an operation that should be called
"branch" anymore.
