From: Corinna Vinschen <[email protected]> As outlined in the thread starting at https://cygwin.com/pipermail/cygwin/2025-December/259055.html, newgrp(1) didn't allow numerical group IDs. While this is in line with the shadow-utils version of newgrp(1), it's not what POSIX allows. Fix up the code and the documentation to be more in line with POSIX.
