git-stash: Make examples clearer
git-stash: Make examples clearer

- Difference between a stash name and a stash message was not clear. For
  example, you cannot do:

      $ git stash save foo
      $ git stash apply foo
      fatal: ambiguous argument 'foo': unknown revision or path not in
      the working tree.

- Difference between stash `apply` and `pop` was not clear
- Make it clearer that all `apply`, `pop` and `drop` can take an
  optional stash name, and that the default name is `stash@{0}`
