[Xmonad] darcs patch: make spawn redirect std* to /dev/null

Sun Sep 23 15:13:40 CEST 2007 l.mai@web.de * make spawn redirect std* to /dev/null spawn'd programs inherit their std{in,out,err} from xmonad. This can interfere with logHook logging because some programs dump debugging output to stdout or stderr. This patch therefore redirects all standard streams to /dev/null when a new program is started.
