*If* we are working around the CRLF conversion issue in git itself,
wouldn't it be much simpler to just:

diff --git a/archive-tar.c b/archive-tar.c
index 20af005..da3d98a 100644

(provided that 'cat' magically does not suffer from the same problem,
and I do think that it does not.)

Anyway, I think it would be better to address the problem on the msysgit
side. Perhaps by providing a gzip of a different vintage (e.g. a
self-compiled one) that does not suffer from the CRLF conversion issue.
