mysql2pgsql.perl update

I spent some time updating mysql2pgsql.perl. Changes were driven by an
attempt to migrate a redmine database. Original code was failing for a
number of reasons (regex recursion explosion, . I was wondering it
there's a more formal / appropriate place to put this. I'd also
appreciate a separate set of eyes on my changes. I grabbed an initial
copy from http://pgfoundry.org/projects/mysql2pgsql/
Git repo of the changes at
