mistake in file sources.list

[Herbert Schulze <schulze.evw@t-online.de>]

I was told that every single line of the file sources.list should 
contain the word "squeeze".
Otherwise I could have problems to actualize my system.

Find below my sources.txt Two lines do not contain "squeeze"!

Thanks for help
