Public bug reported:
It executes the supplied command thusly:
DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1
This should be
DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@"
Leaving the caller to redirect stderr to stdout, or to supply a single
fd at their discretion. The side effect of munging the two fd's together
is that programs which provide structured data on stdout have their
output streams corrupted if they, or any subprocesses they have, happen
to write to stderr at an inopportune time.
