`git stash push -m foo` uses "foo" as the message for the stash. But `git stash push -m"foo"` does not parse successfully. Similarly `git stash push --message="My stash message"` also fails. The stash documentation doesn't suggest this syntax should work, but gitcli does and my fingers have learned this pattern long ago for `commit`. Teach `git stash` to parse -mFoo and --message=Foo the same as `git commit` would do. Even though it's an internal function, add similar support to create_stash() for consistency.
