diff 2.8.1 and blank/white space

[Charlton Wang]

Hi,

I seem to be encountering some weird behaviour with diff 2.8.1. I'm  
passing diff the -Bbw arguments and expecting that white space lines  
will be ignored. It seems that this works in general but if the second  
file has more white space lines than the first AND the last whitespace  
line encountered isn't simply a blank line (i.e. just a \n), diff  
flags the files as being different. Here are inputs to demonstrate the  
difference:




[402] diff -w -b -B diff1.txt diff2-works.txt
[403] diff -w -b -B diff1.txt diff2-broken.txt
14a15,18

>
[404] diff -w -b -B diff2-works.txt diff2-broken.txt
[405]


The only difference between diff2-works.txt and diff2-broken.txt is  
the presence of a space character in the second to last line (i.e. the  
last whitespace line).

Thanks,
Charlton
