[PATCH v2 2/3] stash: Allow git stash branch to process commits that look like stashes but are not stash references.

[Jon Seymour <jon.seymour@gmail.com>]

This patch allows git stash branch to work with stash-like commits created by git stash create.

Two changes were required:

* relax the pre-condition so that a stash stack is required if and only if a stash argument is not specified
* don't attempt to drop a stash argument that doesn't look like a stash reference.
