While we don't want to make it _easy_ for users to shoot themselves in the foot, neither do we want to make it difficult or impossible for them to get the tool to do things that _might_ be a mistake. And what's the risk here? Accidentally committing too much is not a destructive change, and can be easily undone.

Yes I have occasionally committed more than I meant to, but rarely much more, and almost never due to using "git commit -a", seeing as I hardly ever use it. I am of the "commit early and often" school, and my most common pattern is committing tiny batches of changes which I review frequently with "git diff" and then again by staging them with "git add --patch" (aliased as "git patch" seeing as I use it so often).

Are you not a big fan of "subject line + justification" commit message format? Consider it one of the perks of using the format: your editor will show you a nice summary that gives you yet another chance to double-check what you're about to commit.

Cheers,
