unsigned, with 'verbatim', they will be silently exported
and with 'warn', they will be exported, but you will see a warning.
+--tag-of-filtered-object=(abort|drop|rewrite)::
+ Specify how to handle tags whose tagged objectis filtered out.
+ Since revisions and files to export can be limited by path,
+ tagged objects may be filtered completely.
++
+When asking to 'abort' (which is the default), this program will die
+when encountering such a tag. With 'drop' it will omit such tags from
+the output. With 'rewrite', if the tagged object is a commit, it will
+rewrite the tag to tag an ancestor commit (via parent rewriting; see
+linkgit:git-rev-list[1])
+
-M::
-C::
Perform move and/or copy detection, as described in the
allow that. So fake a tagger to be able to fast-import the
output.
+[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.
