migrate_from_trac: convert TracQueries into Redmine's Custom Queries
Do we see that as technically feasible?
There are two ways to use TracQueries in Trac - embedding the query as a TracLink, and using a TicketQuery macro (see http://trac.edgewall.org/wiki/TracQuery for details).
Their syntax is quite straightforward - can we parse them when encountered in Trac Wiki pages, and save as Custom Queries during import? (and place a link to the original place of course).
