[PATCH] git-rebase-script: rebase local commits to new upstream head. Using git-cherry, forward port local commits missing from the new upstream head. This also depends on "-m" flag support in git-commit-script. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Big tool rename. As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more. The commands installed do not have any such suffix so users do not have to remember if something is implemented as a shell script or not. (2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

Redo "revert" using three-way merge machinery. The reverse patch application using "git apply" sometimes is too rigid. Since the user would get used to resolving conflicting merges by hand during the normal merge experience, using the same machinery would be more helpful rather than just giving up. Cherry-picking and reverting are essentially the same operation. You pick one commit, and apply the difference that commit introduces to its own commit ancestry chain to the current tree. Revert applies the diff in reverse while cherry-pick applies it forward. They share the same logic, just different messages and merge direction. Rewrite "git rebase" using "git cherry-pick".
