This is a good idea. Maybe .decorate could have two arguments, one for the 
decorations and one for the effect on space or punctuation. They could be 
binary coded like the argument for .hy, so one could combine them. No argument 
or argument 0 (Zero) would switch it off.

(E.g. for first argument 1 is underline, 2 is strike through, 3 is both; for 
second argument 1 is apply on space, 2 is apply on punctuation, 3 is both an 0 
is apply on characters only.)
