[PATCH] xauth writes incomplete .xauth file and deletes old one whendisk full

[Mike A. Harris]

The attached patch fixes a bug where xauth may write an
incomplete .xauth file and delete the old one if there is
insufficient disk space.  The patch applies cleanly to CVS head, 
xf-4_2-branch, and xf-4_1-branch and is tested.
