Well, that is sure vindictive. Either they don't know they have that  
setting, in which case, "meh",
or perhaps they have that set in order to work with some older tools,  
in which case why should Mercurial deliberately get in their way?

Frankly I don't see why Mercurial has to be a piss-ass about this,  
Python itself deliberately permits handling \r endings with aplomb.
