Re: [PATCH] mergetools: implemented new mergetool file for ExamDiff

We can probably do this without introducing a new file.  One
possible home for this is with the rest of the "default"
definitions of the functions in git-mergetool--lib.sh's
setup_tool() function.

But, that hints that we expect tools to override it.

A better place would be as a normal function inside
git-mergetool--lib.sh, which more strongly hints that we do not
expect tools to override mergetool_find_win32_cmd().

Thanks for a clearly described set of rules that people can easily
follow.
