We've gotten a lot of confusion recently about messages not accepting wikitext.  It would 
probably make more sense for the messages to decide whether they accept wikitext (or whether they 
should be escaped, etc., etc.), as opposed to the caller.  After all, it would be kind of 
ridiculous for one call to allow wikitext and another not to.

This could then be leveraged during preview to show the message as it will actually appear, and 
during edit to put a nice little message at the top of the screen.  Also, maybe it would even 
give us an excuse to start phasing out wfMsg and friends for something sensible: classed, with 
coherent options, only one way to do one thing, parameters passed as arrays (maybe even keyed 
parameters rather than just numbered?) and not with get_func_args().
