Subject: Stop showing __BULK_INSERT__  during populate() without bindvals
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=455636bc6be342d8a733960490f1767eb3e929d8;p=dbsrgits%2FDBIx-Class-Historic.git

Stop showing __BULK_INSERT__  during populate() without bindvals

Also restructure the code a bit (e.g. avoid a useless list-copy)
