We don't need '-merged-file', 'save as', and the merge-status exit

[PATCH 3/3] mergetool-lib: add diffuse as merge and diff tool

[David Aguilar]

From: Sebastian Pipping <sebastian@pipping.org>

This adds diffuse as a built-in merge tool.

Signed-off-by: Sebastian Pipping <sebastian@pipping.org>

This is Sebastian's patch rebased onto Junio's pu branch.

I removed the git-gui part because I think git-gui
patches go through Shawn / git-gui.git?


This diff is still too big, so maybe we should
refactor the $mergetool_candidate code into
mergetool-lib as well.

Hi Sebastian..
Here's the patch you sent a couple of days ago applied
onto Junio's pu branch

As I mentioned above, you had some git-gui changes in your
original that I stripped out since I was under the impression
that git-gui patches go through Shawn / git-gui.git.

git-send-email (probably gmail, too) won't let me send
one patch in a series with a different "From:" header,
so maybe you should resend this patch so that you can get the
proper authorship recognition?  I've attached the original
patch file I sent in case you want to just grab it and
send-email it back out for the purposes of getting the right
authorship in there (actually, Junio, please advise...,
I'm not exactly sure what you'd prefer)


Also, all three patches should apply independently,
so even though this says 3/3 in principle they are
actually all independent patches,
I just happened to have them queued up that way.

The way you marked your 3/3 with a From: line in the body of the message
is the preferred way to say "David forwards a patch from Sebastian", and
our patch application tool knows about it.

If you wanted to preserve the original author date, you could have also
added a Date: line in-body ("David forwards a patch from Sebastian, who
created it at this date in this timezone").  You can find an earlier
example in:

I guess the same as for xxdiff and kdiff3 also applies to opendiff,
ecmerge and emerge. But since I don't have them installed, I'm not
entirely sure not to break something.
On the other hand it should be save, since they were just copied from
git-mergetool without adjustment for diff use.

I have opendiff on a mac at work so I'll give it a test there
and send a patch once it's working.
