Move point to the end of the buffer.
With numeric arg N, put point N/10 of the way from the end.
If the buffer is narrowed, this command uses the end of the
accessible part of the buffer.
If Transient Mark mode is disabled, leave mark at previous
position, unless a C-u prefix is supplied.
Don't use this command in Lisp programs!
(goto-char (point-max)) is faster.
