Re: [PATCH] Only use GIT_CONFIG in "git config", not other programs

Hmm, I actually think this is a good thing to do in the sense that it
vastly simplifies the user experience ;-).  Two less things to explain.

Care to write up a snippet for 1.6.0 release notes, as this is quite a
large user visible backward incompatible change, even though it would be
an improvement?
