diff-bug

[Lukas Cerman]

Hi!

I discovered a weird bug in diff output -- some common lines are 
reported different, and are included in just following difference.

See sixth difference in file diff-2.8.1-b produced by comparing files 
worker1.cpp and worker2.cpp (diff -b worker1.cpp worker2.cpp):

132,136c183,906
<   char number[50];
<   CQuadWord size;
<   DWORD err;
<   if (SxxGetFileSize(file, fileName, size, err)) NumberToStr(number, 
size);
<   else number[0] = 0;  // chyba - velikost neznama

size);

First five lines are obviously the same. Different -- but also incorrect 
-- output is done by command `diff worker1.cpp worker2.cpp', which I 
saved in file diff-2.8.1.

I've also tried it with version 2.7, without option -b it worked fine!! 
Using option -b it produced the same output as version 2.8.1.

Here is, what my diff says 'bout itself:
