Re: please implement query-exchange

[Dan Jacobson]

Anyway, how about we dispose of my bug by merely adding to the
query-replace Info pages:

  But what if you want to say, _exchange_ x and y: replace x's with
  y's, but at the same time replace y's with x's?  Well, try something
  like
  (query-replace "x" "@TEMP@")
  (query-replace "y" "x")
  (query-replace "@TEMP@" "y")
