[MERGE] Refactor diffing

[Marius Kruger]

hi,
thanks for doing this.

Some time ago I thought about writing a plugin that can do whitespace-diff
and whitespace-status
to be able to see only whitespace changes and nothing else, in stead of
reading through a
long diff which is the case when using cdiff --check-style.

When I looked at the diff code back then I realised it wouldn't be so easy
to change the diff
algorithm, so I parked it.

I'm guessing that this change will make that sort of thing a lot easier,
I would just have to somehow register my whitespace differ for that command,

and have to get it to ignore binary files IIUC.

regards
marius
