 By default, Emacs printing functions (like `prin1') print unreadable
 objects as \"#<...>\", where \"...\" describes the object (for
-instance, \"#<marker in no buffer>\").  If this variable is non-nil,
-it should be a function which will be called to print the object instead.
-
-The function will be called with two arguments: the object to be printed, and
-the NOESCAPE flag (see `prin1-to-string').  If this function returns nil, the
-object will be printed as usual.  If it returns a string, that string
-will then be printed.  If the function returns anything else, the
-object will not be printed.  */);
