These things (.isdigit(), .isspace(), istitle(), etc) came along with
Unicode support, and indeed for the first time in 1.6.  Answering "is this
is a digit?" is a lot harder in Unicode!  So Python does it for you.  The
same methods were added to regular (8-bit) strings at the same time, for
uniformity.
