    _\bL_\bo_\bo_\bk consults a sorted _\bf_\bi_\bl_\be and prints all lines that begin
    with _\bs_\bt_\br_\bi_\bn_\bg.  It uses binary search.

    The options d\bd and f\bf affect comparisons as in _\bs_\bo_\br_\bt(1):

    d\bd         `Dictionary' order: only letters, digits, tabs and
        blanks participate in comparisons.

    f\bf         Fold.  Upper case letters compare equal to lower case.

    If no _\bf_\bi_\bl_\be is specified, /_\bu_\bs_\br/_\bd_\bi_\bc_\bt/_\bw_\bo_\br_\bd_\bs is assumed with
    collating sequence -\b-d\bdf\bf.\b.
