Emacs changes the permission bits (mode) of a file when writing to a
file that it thinks is write protected.

To repeat the bug:

1) Make a file "foo", and write protect it.
2) Visit the file in emacs.
3) Do cntrl-x cntrl-q to make the buffer writable.
4) Make some changes.
5) Outside of emacs, do "chmod +w foo".
6) Do cntrl-x cntrl-s to save the buffer, and answer yes on emacs' question.

Emacs will now undo the chmod command, making the file write protected
again.
