auto gc again

Hi,

Could we please PLEASE kill this auto gc thing? I've complained about this in the past and disabled it through the gc.auto config entry, however now git seems to be happily auto running gc even with gc.auto=0. So there's probably some new magic I need to know.

But the new magic is really beside the point. Doing this 'for you' is extremely annoying behaviour. I often work on my notebook, so disk is both slow and battery is precious. I DON'T want gc to run automatically, EVER. Not on repos I have had going for ages, not on ones I just cloned. Please bury this silly policy and replace it with a printf() telling me that I may increase my performance by running git gc. Don't just do it. git does not know better.
