Here's a UNTESTED patch on top of the patch I already sent, which allows 
you to do

	[core]
		AutoCRLF = input

and it should do only the CRLF->LF translation (ie it simplifies CRLF only 
when reading working tree files, but when checking out files, it leaves 
the LF alone, and doesn't turn it into a CRLF).

And by "untested" I mean that it looks ok and seems to compile, but I 
really didn't do anything else.
