I have no objections to this, if others feel that this capability ought to be 
in the core, although I think that's debatable; this sort of external-tool 
integration always struck me as an appropriate use for plugins.  Before this 
can happen, however, I need to:

1. add automated tests
2. divide core capabilities (the '--using' option, general setup) from things 
that need to remain user-extensible (the registration of known diff tools).
3. get the code properly reviewed.

and optionally look at folding in the merge-tool capabilities as well.  So I 
need to get a sense of how seriously people want this capability merged into 
the core.
