In 1.8, public_methods et al take an optional argument which
directs that inherited methods are included or not.

$ ruby -rpp -e 'pp Dir.public_methods(false)'
["glob",
 "superclass",
 "entries",
 "pwd",
 "[]",
 "foreach",
 "open",
 "rmdir",
 "delete",
 "getwd",
 "new",
 "mkdir",
 "chdir",
 "allocate",
 "chroot",
 "unlink"]
