I think the reasoning behind these patches is good.

How do we feel about this duplication?
Bad.
Should we make a common function in the git-sh-setup.sh,
or is it okay to have a slightly modified version of this
function in two places?
I'd prefer to have a common function, I just didn't know if there was somewhere appropriate to place it, available from both files. And I'm going to have to learn a bit more sh to get it right.
Also, the "@@DIFF@@" string may not work here.
This is a template string that is replaced by the Makefile.

It does work in git-mergetool--lib.sh, but not in mergetools/p4merge.

We prefer $(command) instead of `command`.
These should be adjusted.

Can the same thing be accomplished using "git diff --no-index"
so that we do not need a dependency on an external "diff" command here?
Do these comments still apply if it's a common function in git-sh-setup.sh that git-one-merge-file.sh will use? I'm wary of layering violations.
