Re: Recommend these .gitconfig settings for git integrity.

[Karl Fogel]

I don't have very strong feelings on the autogen.sh git config change, but I 
think we had consensus about the documentation change anyway, and that is now 
committed:

(Paul, sorry for getting the date wrong by one day, where my commit message 
refers to the earlier of your two autogen.sh commits; I believe the reference 
will be easy to follow for anyone who wants to, though, given all the context.)

I've updated the relevant wiki pages as well.
