That's not a CR (CR is 0d), it's an LF, i.e. newline.  The variable you 
want to customize is require-final-newline.

But why would you want to remove it? Text files should be a sequence of 
lines, and each line should end with a newline. Some programs don't 
process the last line correctly if it doesn't end with a newline.
