@@ -157,6 +157,9 @@ For sorting purposes, fields with numeric values sort in numeric
order (`objectsize`, `authordate`, `committerdate`, `taggerdate`).
All other fields are used to sort in their byte-value order.
+There is also an option to sort by versions, this can be done by using
+the fieldname `version:refname` or its alias `v:refname`.
+
In any case, a field name that refers to a field inapplicable to
the object referred by the ref does not cause an error. It
returns an empty string instead.
