setpgrp 1 user commands nosh
setpgrp become a process group leader then chain
`setpgrp` next-prog

## Description

`setpgrp` is a chain-loading utility that attempts to become a proces group leader and then chain loads to next-prog with the execvp 3 function.

next-prog may contain its own command line options, which `setpgrp` will ignore.

If the process already is a process group leader, no call to the setpgid 2 library function is made.
