bdiff: improve worst case behavior by 100x.
on 5.8MB (244.000 lines) text file with similar lines, hash before
this change made diff against empty file take 75 seconds. this change
improves performance to 0.6 seconds. result is that clone of smallish
repo (137MB) with some files like this takes 1 minute instead of 10
minutes.
common case of diff is 10% slower now, probably because of worse cache
locality. but diff does not affect overall performance in common case
(less than 1% of runtime is in diff when it is working ok), so this
tradeoff looks good.
