[BusyBox] busybox-0.60.1 pidof return exit code

[Max Headroom]

We found that code currently in pidof.c aloways
returns 0( EXT_SUCCESS ) to the calling process.
This makes in impossible to use pidof in
scripts that require an exit status 
to determine if pidof suceeded.
We suggest that the following lines in
pidof.c at about line number 77 be changed
from:
    printf("\n");
    return EXIT_SUCCESS;
to:
    printf("\n");
    if (fail) return EXIT_FAILURE;
    return EXIT_SUCCESS;

We were wondering if there is a reason why the
current version of pidof behaves this way.
It does not appear to be POSIX compliant.

I am attaching a patch file.

Thanks
