protected DiffEngine::_shift_boundaries($lines, &$changed, $other_changed) Adjust inserts/deletes of identical lines to join changes as much as possible. We do something when a run of changed lines include a line at one end and has an excluded, identical line at the other. We are free to choose which identical line is included. `compareseq' usually chooses the one at the beginning, but usually it is cleaner to consider the following identical line to be the "change". This is extracted verba

protected DiffEngine::_line_hash($line) Returns the whole line if it's small enough, or the MD5 hash otherwise.

protected DiffEngine::_diag($xoff, $xlim, $yoff, $ylim, $nchunks) Divide the Largest Common Subsequence (LCS) of the sequences [XOFF, XLIM) and [YOFF, YLIM) into NCHUNKS approximately equally sized segments. Returns (LCS, PTS). LCS is the length of the LCS. PTS is an array of NCHUNKS+1 (X, Y) indexes giving the diving points between sub sequences. The first sub-sequence is contained in [X0, X1), [Y0, Y1), the second in [X1, X2), [Y1, Y2) and so on. Note that (X0, Y0) == (XOFF, YOFF) and (X[NCHU

protected DiffEngine::_compareseq($xoff, $xlim, $yoff, $ylim) Find LCS of two sequences. The results are recorded in the vectors $this->{x,y}changed[], by storing a 1 in the element for each line that is an insertion or deletion (ie. is not in the LCS). The subsequence of file 0 is [XOFF, XLIM) and likewise for file 1. Note that XLIM, YLIM are exclusive bounds. All line numbers are origin-0 and discarded lines are not counted.
