Subject: Upgrade duplicate bugdirs if necessary (e.g. for `be diff').
X-Git-Tag: 1.0.0~62^2~25^2~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5e8576a48fae6e9f7a9699d57571e926d7e6e236;p=be.git

Upgrade duplicate bugdirs if necessary (e.g. for `be diff').

Also moved pre-YAML mapfile handling in mapfile.parse() into
upgrade.Upgrade_1_0_to_2._upgrade_mapfile().
