commit d6a81050ace2630b06c3c6dd39bb4eef5d1043f8
Author: tobias <tobias at openbsd.org>

    partial sync of regress/netcat.c with upstream
    
    The code in socks.c writes multiple times in a row to a socket. If the socket becomes invalid between these calls (e.g. connection closed), write will throw SIGPIPE. With this patch, SIGPIPE is ignored so we can handle write's -1 return value (errno will be EPIPE). Ultimately, it leads to program exit, too -- but with nicer error message. :)
    
    with input by and ok djm
