|FooBar	foobar			
|blaTZ	blatz
|GRMblE	grmble
|WhEe	whee

Just for the record, I really did play around with sed's y operator a bit
and swapping pattern and hold spaces before throwing up my hands and doing
it the easy way.  Use

    % perl -n foo.pl

where foo.pl consists of:

    chop;
    print $_, " ";
    y/A-Z/a-z/;
    print $_, "\n";

I'm not sure how you plan to merge two files, but I think it'll end up
being easier in perl than in sed.
