commit d9869ef79c2e1c549c2b2100b2115b0cdb1d3297

    grep: remove bool_bf
    
    The extra complexity of this microoptimization wasn't ever much help,
    and currently it generated bigger code with gcc -O2 (x86-64).
    * src/dfa.c (bool_bf): Remove.  All uses replaced by plain 'bool',
    without a bitfield.
