[BusyBox] busybox bugfix - wget

[Chip Rosenthal]

There were subtle (minor) problems with "wget -O -".  For instance,
"wget -c -O -" was treated differently from "wget -c".

The attached patch should correct the problem.  There should be no
side effects from the patch.  The correction adds 16 bytes.
