allow that. So fake a tagger to be able to fast-import the
output.
+--no-data::
+ Skip output of blob objects and instead refer to blobs via
+ their original SHA-1 hash. This is useful when rewriting the
+ directory structure or history of a repository without
+ touching the contents of individual files. Note that the
+ resulting stream can only be used by a repository which
+ already contains the necessary objects.
+
+[git-rev-list-args...]::
+ A list of arguments, acceptable to 'git-rev-parse' and
+ 'git-rev-list', that specifies the specific objects and references
+ to export. For example, `master\~10..master` causes the
+ current master reference to be exported along with all objects
+ added since its 10th ancestor commit.
