set the close-on-exec flag for newly opened files

Reason:
 vi uses flock to help you notice when you are already editing a file.

 But, when using :shell or :! the fdesc for the locked file is inherited by
 the subprocess.

 This means that if you (say) do a :!xterm& and then quit vi, the fdesc is
 kept open by the xterm and the lock is never released. future vi's on
 that file will then complain.

 I sent this off to bostic.com a long time ago but have as yet heard nothing.
