Quite contrary, I think the approach outlined is a reasonable way
forward.  I do not care about a checkbox feature like $Id$ that is
incomatible with the fundamental concept in Git, but the approach
would help people who started their history with wrong CRLF
settings, tweak the attributes and then scratch their head trying to
repeatedly run "checkout", "reset --hard", etc. and still never
seeing the right thing to happen.
