Indeed. When I run `git stash`, my intention is to make sure that I can
get back whatever edits I had made, but right now, I want a clean
worktree.
So for me, `git stash` does *the exact right thing*.
I could see, however, that other users might think that it is more like a
"uh oh, I have modifications that I do not want to commit right now!
Please, Git, put all my local changes into a stash", and when there are
not even any changes to stash, they want the command to fail.
However, I think that this is not only a change in behavior, but probably
a minor use case compared to what I feel *my* use case is ;-)
As such, the new behavior should be hidden behind an option (say,
`--fail-if-clean`).

Indeed, the commit message should make a case for the change. Otherwise,
it will be less convincing...
