commit fbad6e79fae1ed12c5d3b5611f490e75066adfad
Author: Rich Salz <rsalz at akamai.com>
Date:   Thu Aug 29 15:37:01 2019 -0400

    Exit non-zero if find-doc-nits finds nits
    
    Filter all output to a new &err() routine, which sets the global
    exit status, $status.
    Also, fix all subroutine definitions and references to be consistent:
    no prototypes, no & before function calls.
