have conflicts (which are stored in the index, where you therefore can no
longer apply the changes as they were originally).
branch <branchname> [<stash>]::
Creates and checks out a new branch named `<branchname>` starting from
the commit at which the `<stash>` was originally created, applies the
changes recorded in `<stash>` to the new working tree and index, then
drops the `<stash>` if that completes successfully. When no `<stash>`
is given, applies the latest one.
+
This is useful if the branch on which you ran `git stash save` has
changed enough that `git stash apply` fails due to conflicts. Since
the stash is applied on top of the commit that was HEAD at the time
`git stash` was run, it restores the originally stashed state with
no conflicts.
clear::
Remove all the stashed states. Note that those states will then
be subject to pruning, and may be difficult or impossible to recover.
