revert: Save data for continuing after conflict resolution Ever since v1.7.2-rc1~4^2~7 (revert: allow cherry-picking more than one commit, 2010-06-02), a single invocation of "git cherry-pick" or "git revert" can perform picks of several individual commits. To implement features like "--continue" to continue the whole operation, we will need to store some information about the state and the plan at the beginning. Introduce a ".git/sequencer/head" file to store this state, and ".git/sequencer/todo" file to store the plan. The head file contains the SHA-1 of the HEAD before the start of the operation, and the todo file contains an instruction sheet whose format is inspired by the format of the "rebase -i" instruction sheet. As a result, a typical todo file looks like: pick 8537f0e submodule add: test failure when url is not configured pick 4d68932 submodule add: allow relative repository path pick f22a17e submodule add: clean up duplicated code pick 59a5775 make copy_ref globally available Since SHA-1 hex is abbreviated using an find_unique_abbrev(), it is unambiguous. This does not guarantee that there will be no ambiguity when more objects are added to the repository. These two files alone are not enough to implement a "--continue" that remembers the command-line options specified; later patches in the series save them too. These new files are unrelated to the existing .git/CHERRY_PICK_HEAD, which will still be useful while committing after a conflict resolution.
