X-Git-Tag: v0.07002~30
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=057d4713af8f97b17a351bca5d11fe55e5a8b88a;p=dbsrgits%2FDBIx-Class.git

Change _cond_for_update_delete to handle more complicated queries through recursing on internal hashes.
Add a test which should succeed and fails without this change.
