[git] How to name and retrieve a stash by name in git?

You can turn a stash into a branch if you feel it's important enough:

git stash branch <branchname> [<stash>]

from the man page:

This 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.

You can later rebase this new branch to some other place that's a descendent of where you were when you stashed.
