Sorry about that, I meant something like

git stash && git checkout develop && git pull && git checkout -b new-feature-branch && git stash pop

My point is that it is the user's expectation that "git stash" will push to the stash.
Not pushing anything should be considered a failure.

I guess that is only half an answer.  If you really want to avoid
creating the new branch when the working tree and the index are
clean, you'd need to check that yourself before that three-command
sequence.  In our shell script, we use these as such a check:

	git update-index --refresh -q --ignore-submodules
	git diff-files --quiet --ignore-submodules &&
	git diff-index --cached --quiet --ignore-submodules HEAD --

But stepping back a bit, why do you even need stash save/pop around
"checkout -b new-feature-branch" (that implicitly branches at the
tip) in the first place?  "checkout -b" that begins at the current
HEAD does not touch the index nor the working tree and take the
local changes with you to the new branch, so save/pop around it
seems totally pointless.
