Since it is a temporary thing, and not user-visible, I would opt for git-add--helper.

I think it's fine. There has been a patch series consisting of ~80 individual patches before, as long as you do not go close to that one, I think you are fine. > Another regret I had was not being able to retire any code from the Perl > script yet (and will likely not be able to do so until all commands have > been ported), but that is not such a big thing after all. All in due time. But maybe you want to keep the naming a little more consistent with the Perl script, e.g. instead of calling the function `print_modified()` call it already `list()` (and rename it later to `list_and_choose()` once you have taught it to ask for a choice)? > As for the new builtin, I think the color handling code is pretty > straightforward.

The same goes for the pretty > simple option parsing code. True. It does look awfully similar to other code handling colors. Maybe put it on the backlog.

I would actually think that the callback Junio talked about would be more appropriate than to write temporary files. Even to split the diff. We can do that much more efficiently in-memory. > My first instinct was to create something like > show_numstat_interactive() or something on diff.c (analogous to the > other show_* functions).
