Ruby 1.8.7 has that method.

ruby 1.8.7 (2009-06-12 patchlevel 174) [x86_64-linux]
$ ruby -e 'puts String.new.respond_to?(:grep)'
true

docs for parent classes, but it is at least an easier way of figuring 
out where inherited methods come from.

reason to upgrade to 1.9! Now if only I can convince my hosting 
providers to do so...
