MFC r197371: Mention that NUL characters are not allowed in sh(1) input.

I do not consider this a bug because POSIX permits it and argument strings and environment variables cannot contain '\0' anyway.

PR: bin/25542

------------------------------------------------------------------------

Recently I have been noticing strange happenings of what I believe to be coming from the latest revision of /bin/sh. Prior to this revision it had not happened to the following examples. I am taking this as it could just be a following behavior in sudo due to fixing the first behavior in sh(1) but I am not sure and looking for feedback.

How to repeat: ( Let me know if this is only me. )
# sudo rm -rf /usr/ports/*/*/work

After issuing the above command the process waits for the list of (work) directories to be collected and ends by bombing out with pam timeout error. This could probably be easier seen with higher IO load but it has struck me kind of odd since I have not seen it at all till now. Also once it gets started you can not ^C the process until it has run the full directory tree.

Behavior before, you could issue the command and it would ask you for your password before it would issue any IO to the disk. Is the new behavior called for adjusting your command to sh -c "rm -rf /usr/blah/bloo/bla*" ?

Thanks
