[Dlang-internal] What git settings should I use when working on the compiler for line endings?

(I didn't see this in the contribution pages, so apologies if I 
skimmed it too fast)

I'm developing on a linux box.  I see that when I git cloned the 
project all the line endings got changed.  I don't want to commit 
files with only changed line endings.  You probably have a 
preferred setting of a git internal config variable to prevent 
problems.  What do you set it to?
