Re: [PATCH] blame: avoid -lm by not using log().

According to my late-night maths skills, these two methods do not do the 
same thing: if num_blame_lines == 9, the log method assigns 2 to 
max_digits, but the for loop stops at max_digits == 1. A trivial fix would 
be to test for i <= num_blame_lines + 1.
