Rev 2.6.1 answer wrapper?

[Frank Leahy]

I downloaded Rev 2.6.1 and noticed that on OS X it displays answer 
dialogs (e.g. Save this stack?) with multi-sized text (i.e. different 
sizes for the primary and secondary text strings), and in the correct 
system font. Nice!

Does anyone know if they wrote their own wrapper around the built-in 
answer routine to handle font sizing, line breaks, creation of html 
text, etc., and if so what the name of the routine is?  I'd rather call 
their routine instead of having to reinvent my own.
