Merge branch 'jk/clone-copy-alternates-fix'

"git clone" of a local repository can be done at the filesystem
level, but the codepath did not check errors while copying and
adjusting the file that lists alternate object stores.

* jk/clone-copy-alternates-fix:
clone: detect errors in normalize_path_copy
