The usual philosophy in Git is not to bother the user with
confirmations, but to allow recovery after a mistake.
If you've moved a branch pointer around (e.g., via "git branch -f" or
"git reset"), you can recover it from the reflog.
In the case of a mistakenly dropped stash, there's no reflog (the stash
list itself is implemented as a reflog!), but you can use "git fsck" to
generate a list of "dangling" commits. These are commits which are
unreferenced, but they hang around until at least the next git-gc run.
Note that there _are_ some commands which are not reversible: mostly
things that drop content from the working tree. So "git reset --hard" is
one, and "git clean" is another. There have been discussions and even
some patches about storing the lost in an "undo log", but nothing has
been merged.
