* lisp/files.el (find-alternate-file): If the old buffer is modified

  and visiting a file, behave similarly to `kill-buffer' when killing
  it, thus reverting to the pre-1.878 behavior; see
  http://lists.gnu.org/archive/html/emacs-devel/2009-09/msg00101.html
  for discussion.  Also, consult `buffer-file-name' as a variable not
  as a function, for consistency with the rest of the code.
