This is how I have it setup as well and both diff and merge work for
me.  I had to do a weird thing with passing it $LOCAL twice if there
was no merge base since otherwise it does a diff tool instead of a
merge tool - the difference is based on the number of arguments, but
it seems to work pretty well.  I can try it on Linux a bit later, but
I'm not sure why launchp4merge would be needed instead of setting the
path like this on a Mac - if there is no serious objection, I can
resend this with my Signed-Off-By (sorry, I forgot).

Thanks,
Scott
