Then Junio and I are in disagreement. IMO, Git does not have to be more 
clever than the pager when it comes to presentation of text.

Yes, I think so. As long as I'm not telling Git that my files are CRLF 
when they actual are, then the CR before LF is a whitespace error. 
Nevertheless, I do *NOT* want Git to outwit my pager by inserting 
<RESET> between CR and LF all the time so that it is forced to treat the 
lone CR like a control character that is to be made visible.

I'm suggesting that users who knowingly store CRLF files in the 
database, but do not want to see ^M in added lines have to use 
whitespace=cr-at-eol and that's all. I do not see inconsistency.
