revert: triage "deleted" files into more appropriate categories...

revert: triage "deleted" files into more appropriate categories Status can return file as "deleted". This is only a special case related to working directory state: file is recorded as tracked but no file exists on disk. This will never be a state obtainable from manifest comparisons. "Deleted" files have another working directory status shadowed by the lack of file. They will -alway- be touched by revert. The "lack of file" can be seen as a modification. The file will never match the same "content" as in the revert target. From there we have two options: 1. The file exists in the target and can be seen as "modified". 2. The file does not exist in the target and can be seen as "added". So now we just dispatch elements from delete into appropriate categories.
