 Additionally, even though line #2 is relatively short, vi still fails to 
 handle it properly.  It displays a couple of large chunks of the text as 
 "^@" (ie, NUL) characters.  Using hexdump, I have verified that these 
 NUL characters are not part of the input file.
 
 I have attached the 2215-character input file as well as a cat-and-paste 
 of the display output.
