Subject: | [PATCH] DBIx::Class::Row->discard_changes documented twice |
There are two documentation hunks in DBIx::Class::Row for the discard_changes method, with
overlapping content. The attached patch merges the two together, preserving all content except
for the (outdated) claim that the method is actually implemented in DBIx::Class::PK.
