It may need some serious tweaking, because {(...)} always
expects the operation to be at the front, while {( ? : )} seems
to have its operators in the middle.  If I were doing this
from scratch, I would probably write it as:

  {(if cond true false)}

Then the above would be written as:

  Christmas is {(if (gt 2007-12-25 (ftime %F)) "coming!" "past!")}

I didn't realize that SelectQuery was using {(...)} as a 
markup sequence, so my profound apologies if this development 
is now clobbering that.  I think I would head towards the 
{(if ...)} approach -- I think it's slightly less cryptic,
and we also don't have to worry about " ? " and " : " accidentally
appearing in the text somewhere as the result of another substitution.

But whatever you choose to do is great with me, and if I can
help resolve any conflicts, let me know.
