This patch updates diff documentation and usage strings: - clarify the semantics of -R. It is not "output in reverse"; rather, it is "I will feed diff backwards". Semantically they are different when -C is involved. - describe -O in usage strings of diff-* brothers. It was implemented, documented but not described in usage text. Also it adds -O to diff-helper. Like -S (and unlike -M/-C/-B), this option can work on sanitized diff-raw output produced by the diff-* brothers. While we are at it, the call it makes to diffcore is cleaned up to use the diffcore_std() like everybody else, and the declaration for the low level diffcore routines are moved from diff.h (public) to diffcore.h (private between diff.c and diffcore backends).
