- 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}`
