commit 8ea1c520a237586f2c1909c7b9cd3223414a5d1c
Author: Jim Meyering <address@hidden>
Date:   Fri Oct 31 18:40:50 2014 -0500

    build: generate man pages even when existing targets are read-only
    
    * doc/Makefile.am (grep.1): Use mv -f to move temporary to target,
    in case the target is read-only.  Also, always make the generated
    files read-only.
    (egrep.1 fgrep.1): Likewise.
    This avoids a build failure reported by Eric Blake in
    http://lists.gnu.org/archive/html/bug-grep/2014-10/msg00112.html
