Speaking for mergetool, I believe that it's simply because mergetool
uses git cat-file which just outputs the raw contents of a blob and
doesn't do any line ending conversion.

IMHO, I think that it should probably perform the 'convert to working
tree format' change when preparing the temporary files. I'm not sure
how best to do that, but perhaps it should be using git checkout-index
with the --temp option instead of cat-file.
