I suspect that is not what the implementation intends to do.
"list -n 4", "list --since=1.hour" would make sense, but "list
stash@{12}" would probably not.

Is that what it does? I had an impression that "show stash@{2}"
shows a regular diff between the base and the stashed working
tree state.

The implementation appears to apply on a clean index without
restriction to where the HEAD is. I hinted that that behaviour
is fine in my previous message, but on the other hand haven't
convinced myself enough to say that it would not confuse end
users. Maybe insisting on not just clean index but no changes
from the HEAD would reduce confusion? I dunno.

Probably this should be defined in DESCRIPTION, along with the
definition of what a stash is ("records the difference between
the HEAD when the stash was created and the working tree state
in such a way that it can be applied to a different state
later").
