[BusyBox] env - <command> -<opt> bug: env tries to eat -<opt>

[Denis Vlasenko]

# ./busybox env - echo zzz
zzz
# ./busybox echo -n zzz
zzz
# ./busybox env - echo -n zzz
env: invalid option -- n

	instead of blindly passing it to echo...

BusyBox v1.00-pre1 (2003.07.16-07:53+0000) multi-call binary
