[PATCH 0/6] Support applying patches in a new worktree

[Kyle Meyer <kyle@kyleam.com>]

This series is prompted by simon's patch workflow described at
<https://yhetil.org/guix-patches/86361cys9h.fsf@tournier.info>:

With patch 4, something like that should be possible with both piem-am
and piem-b4-am-from-mid.  When the new piem-am-create-worktree option
is set to a non-nil value, the caller will be prompted for a directory
where the new worktree should be created.

Patch 5 makes it possible to trigger this in a one-off fashion with a
prefix argument because, while I don't want this behavior most of the
time, I could see myself using it every now and then.
