[PATCH 0/8] build-in add -i: implement all commands in the main loop

Based on the js/builtin-add-i branch, this patch series implements the rest of the commands in git add -i's main loop: update, revert, add_untracked, patch, diff, and quit. Apart from quit, these commands are all very similar in that they first build a list of files, display it, let the user choose which ones to act on, and then perform the action.

Note that the patch command is not actually converted to C, not completely at least: the built-in version simply hands off to git add--interactive after letting the user select which files to act on.

The reason for this omission is practicality. Out of the 1,800+ lines of git-add--interactive.perl, over a thousand deal just with the git add -p part. I did convert that functionality already (to be contributed in a separate patch series, see https://github.com/gitgitgadget/git/pull/173), discovering that there is so little overlap between the git add --patch part and the rest of git add --interactive that I could put the former into a totally different file: add-patch.c.

Johannes Schindelin (8):
  built-in add -i: allow filtering the modified files list
  built-in add -i: prepare for multi-selection commands
  built-in add -i: implement the `update` command
  built-in add -i: re-implement `revert` in C
  built-in add -i: re-implement `add-untracked` in C
  built-in add -i: implement the `patch` command
  built-in add -i: re-implement the `diff` command
  built-in add -i: offer the `quit` command
