commit a25effe4c8ffcc34a1698459f5a1e43df1e11c31
Author: Paul Eggert <address@hidden>
Date:   Wed Feb 8 11:17:35 2012 -0800

    tests: work portably even if SIGPIPE is ignored
    
    * tests/epipe: Don't rely on "trap - PIPE"; that's not portable.
    Problem reported by Eric Blake in
    <http://lists.gnu.org/archive/html/bug-grep/2012-02/msg00017.html>.
    Also, use "ls -al" rather than "echo", in case "echo" is done by a
    buggy shell that ignores write errors.  And close grep's fd 3, as
    a sanity check.
