Sounds very handy.  If a user reads the top level function definitions 
or tutorials on Plot, will he or she encounter a sentence like, maybe,

"The options Piecewise and Exclusions can be useful when displaying 
functions that contain discontinuities or breakpoints."

(with the command names being links) so they can learn that these 
particularly useful capabilities exist?
