Following discussions in &lt;https://issues.guix.gnu.org/43893&gt;, keeping a copy
of the updated package source is desirable when generating a release.

* build-aux/update-guix-package.scm (version-controlled?): Remove variable.
(call-with-temporary-git-worktree): Renamed from
'with-temporary-git-worktree'.  Update doc.  Do not change directory
implicitly.  Define as a procedure, not a syntax.
(keep-source-in-store): New procedure.
(main): Adjust to use with call-with-temporary-git-worktree.  Add the sources
to the store when GUIX_ALLOW_ME_TO_USE_PRIVATE_COMMIT is set.  Exit gracefully
when FIND-ORIGIN-REMOTE returns #f.
(%savannah-guix-git-repo-push-url-regexp): Adjust match for a potential colon
separator.
* Makefile.am (GUIX_ALLOW_ME_TO_USE_PRIVATE_COMMIT): Adjust.
* .dir-locals.el (scheme-mode): Remove entry for with-temporary-git-worktree.
* doc/contributing.texi (Updating the Guix Package): Update doc.

Fixes &lt;https://issues.guix.gnu.org/43893&gt;.

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.
