Marc's reply to this thread seems to suggest he has had a great 
experience with this feature disabled, because "the rest of git's 
auto-gc machinery is now working quite well (compared to when git-gui 
was first introduced)".

I personally am not very familiar with the details of Git's auto-gc, and 
Googling around didn't really give out any promising results.

What I gather from reading the man page is that "some commands" run 
git-gc automatically. There isn't much mention of which those commands 
are. But you say that plumbing does not trigger auto-gc, so it would not 
get triggered by people using git-gui.

So here's what I propose: why don't we try to do something similar? What 
about running `git-gc --auto` in the background when the user makes a 
commit (which I assume is the most common operation in git-gui). This 
would be disabled when the user sets gc.auto to 0.

This way, we keep a similar experience to the command line in case of 
auto-gc, and we get rid of the prompt. People who don't want 
auto-compression can just set gc.auto to 0, which they should do anyway.

Thoughts?
