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.

#Test bug regarding symlinks that showed up in hg 0.7
#Author: Matthew Elder <sseses@gmail.com>

#make and initialize repo
hg init test; cd test;

#make a file and a symlink
touch foo; ln -s foo bar;

#import with addremove -- symlink walking should _not_ screwup.
hg addremove

#commit -- the symlink should _not_ appear added to dir state
hg commit -m 'initial'

#add a new file so hg will let me commit again
touch bomb

#again, symlink should _not_ show up on dir state
hg addremove

#Assert screamed here before, should go by without consequence
hg commit -m 'is there a bug?'
