because the checkout was interrupted.  As a result, when this happens
for the Guix checkout, users would not get substitutes for ‘guix pull’.

* guix/git.scm (delete-untracked-files): New procedure.
(switch-to-ref): Use it.
* tests/git.scm ("update-cached-checkout, untracked files removed"): New
test.

it returns the OID of the commit object in all cases.

'tag-target-id' and 'tag-lookup' when OID designates an annotated tag.
