            Refresh the index record(s) of artifact(s) from their folders, changing no file.

            The meta file of each artifact is read from its folder on disk and the artifact's record in the
            index of the category is rewritten from it: the alias is the folder's name, every other alias
            that still pointed at the artifact's UID is dropped, and the path, the meta and the sharding
            depth are what a full `cx --reindex` records. The meta file is read, never written (an empty
            `update` rewrites it). Use it after a meta file was edited by hand, after a folder was renamed,
            moved or copied in from another machine, or when a lookup looks stale - instead of the whole
            `cx --reindex`.

            The artifact may be named by its alias, UID, alias,UID or repo:alias, with wildcards; nothing
            names every artifact of the category. A folder the index does not know yet (made or renamed by
            hand) is found on disk in the repositories; an artifact whose indexed folder is gone is looked
            for by its UID in its repository. No folder is touched, and the only record ever removed is
            that of an artifact whose folder, still there, holds another artifact now (replaced by hand) -
            said in the output. A folder that cannot be found, a meta without a valid `artifact` UID, or a
            UID found in two existing folders is an error, and the index is left as it was
            (`--ignore_errors` reindexes the other artifacts and reports these).
