+--show-original-ids::
+       Add an extra directive to the output for commits and blobs,
+       `original-oid <SHA1SUM>`.  While such directives will likely be
+       ignored by importers such as git-fast-import, it may be useful
+       for intermediary filters (e.g. for rewriting commit messages
+       which refer to older commits, or for stripping blobs by id).
+
 --refspec::
        Apply the specified refspec to each ref exported. Multiple of them can
        be specified.
