           _B_d_i_f_f is used in a manner analogous to _d_i_f_f(1) to find which
           lines must be changed in two files to bring them into
           agreement.  Its purpose is to allow processing of files
           which are too large for _d_i_f_f.  _B_d_i_f_f ignores lines common to
           the beginning of both files, splits the remainder of each
           file into _n-line segments, and invokes _d_i_f_f upon
           corresponding segments.  The value of _n is 3500 by default.
           If the optional third argument is given, and it is numeric,
           it is used as the value for _n.  This is useful in those
           cases in which 3500-line segments are too large for _d_i_f_f,
           causing it to fail.  If _f_i_l_e_1 (_f_i_l_e_2) is ----, the standard
           input is read.  The optional ----ssss (silent) argument specifies
           that no diagnostics are to be printed by _b_d_i_f_f (note,
           however, that this does not suppress possible exclamations
           by _d_i_f_f.  If both optional arguments are specified, they
           must appear in the order indicated above.

           The output of _b_d_i_f_f is exactly that of _d_i_f_f, with line
           numbers adjusted to account for the segmenting of the files
           (that is, to make it look as if the files had been processed
           whole).  Note that because of the segmenting of the files,
           _b_d_i_f_f does not necessarily find a smallest sufficient set of
           file differences.
