control information.  It supports a range of protocols and over a dozen USB
devices.  It can run as a standalone service, which is useful for converting
signals between protocols, or alternatively using the OLA API, it can be used
as the backend for lighting control software.  OLA runs on many different
platforms including ARM, which makes it a perfect fit for low cost Ethernet to
DMX gateways.")

This changes the 'update-guix-package' tool so that it:

1. Always uses a clean checkout to compute the hash of the updated 'guix'
package.
2. Ensures the commit used in the updated 'guix' package definition has already
been pushed upstream.

* build-aux/update-guix-package.scm (%savannah-guix-git-repo-push-url): New
variable.
(with-input-pipe-to-string, with-temporary-git-worktree): New syntaxes.
(find-origin-remote, git-add-worktree): New procedures.
(commit-already-pushed?): New predicate.
(main): Check the commit used has already been pushed upstream and compute the
hash from a clean checkout.
* doc/contributing.texi (Updating the Guix Package): Document it.
* .dir-locals.el (scheme-mode): Fix indentation of with-temporary-git-worktree.
