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.

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path = /real/path
# virtual/path = /real/path
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.

# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
