bug#499: 23.0.60; minibuffer tab completion regression

Indeed, it does now: it constrains the list of possible completions to
those that include the text after point.

E.g. if your minibuffer is "/foo/bat.c" you can place point after "bat"
and hit TAB to complete to a filename among "bat*.c".

You can get the old behavior with one of the following:
- C-k TAB C-y
- customizing completion-styles: you can for example replace `basic' by
  `emacs22' to get back Emacs-22's behavior.  Note that if you select
  `emacs21' you won't get this behavior since Emacs-21 (and all previous
  Emacs) did not ignore the text after point.
