problem with grep -vl

[Mark Perry]

Hello,
in the output below the grep option "-l" is used both with and with the 
option "-v".

In the first example the "grep -l" locates the files that contain the 
string "QETH_OPTIONS", note these 3 files end 0600,0700,0800.

In the 2nd example the "grep -vl" locates _ALL_ files because the 
previously matching string in not in the first line of any of the files.
Note that it again lists files ending 0600,0700,0800 even though we know 
from example 1 that these files _DO_ contain the match string.

I know that "-l" is suppose to stop on the first match, but when combined 
with "-v" should it not search all lines for a possible match?
