Not only that, it's a differentiating feature of Git and it sets it apart from other SCMs, in a good way. We could mindlessly homogenize to be more like other systems, or less "surprising" for users coming from other systems, but we'd be throwing away something valuable in the process. > > If I would ask to disable the indexing feature then you would have a > point.

I _like_ that Git's different, and over the years have become so used to the benefits that working with the index "the Git way" bring, that it's hard to imagine how I ever lived without it. >> >> Cheers, >> Wincent > > I personaly have to work with different SCMs every day and every time I > have to switch minds to work with each specific one. Making git commit > work less surprising would be one less thing to keep in mind. You are trying to make Git more difficult to understand for the user. This is easily perceived as non-determinism. Before introducing a code branch (à la "if $(git diff-index --quiet HEAD)", think twice. It doubles testing efforts, it makes explanations long-winded. What's so difficult about typing [Arrow-Up] [Space] [-] [a] [Enter] if git commit comes up empty. With your option, I need to remember that Git is overzealous and will commit the whole index if nothing is staged, possibly git reset HEAD^ and clean up the mess. This is inconsistent and inefficient. Try git gui or git citool if you can't be bothered to remember how to add changes to your commit. Git isn't alone. Think BitKeeper, DARCS. For other systems, there are extensions to help with committing, and to emulate what DARCS has pioneered, for instance "hg record", an extension for Mercurial. > You like that Git is different so don't use the --a-if-empty option.

If Git itself can't do it, tossing a dozen shell lines into git's libexec would do the job. git diff-index --quiet is your friend.
