Because of this:

+    def charnum(count):
+        return int(round(count*width/maxcount))

Earlier this was "int(count*width/maxcount))", which lead to problem when you
can have something like that:

user1 +x/-x ++--
user2 +x/-x +-
user3 +x/-x +--

i.e. sum of changed lines of user2 is bigger than user3, but it's
distributed in the way
that flooring (instead of rounding) will draw less characters.
