This mail made me see an issue with your patch series. Sorry, I haven't
seen this earlier, my review was just scratching the surface, I merely
applied it and looked through it, but didn't actually test it. Lack of
time.

The invocations seem to be appropriate only for mergetool, it is just
the invocations from the old git-mergetool.sh, not from the old
git-difftool-helper.sh. This means, git-difftool opens 3 files instead
of 2.

I think there are preset diff tools, which opened 3 files instead of 2
before this series (I just tested kdiff3, it opened 3 files). Seems to
be originated from the fact, that they were initially copied from
git-mergetool.sh.
