Aah, that certainly clears things up a bit. A good patch I'd say.

However, it doesn't change the fact that IMO "git show" should respect 
core.autocrlf, while "git cat-file" shouldn't.

I think many would consider
     git show MERGE_HEAD:file.txt > file.txt
before
     git checkout MERGE_HEAD file.txt
if only because they'd be scared to do a "checkout" in the middle of a 
merge conflict.

Personally I think the latter is nice, short and sweet, but that doesn't 
mean that it's less scary for people staring out on git. The fact that 
the two commands above are *not* identical in result, are the kind of 
things that we need to iron out, to make git more accessible to the 
general public.
