Please write commit message in an imperative tone.
e.g. "mergetools: add support for ExamDiff" might be a good summary.

This patch is doing two things.
It's probably worth breaking this patch up into two parts.
Patch 1 can add add the new helper function and update
winmerge to use it.
Patch 2 can add the new examdiff helper.

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().

It might nut hurt to write this as,
printf '%s' "$executable"
For consistency and future-proofing.

If we move the definition into mergetool--lib then we do not
need to dot-include any files here -- it'll simply be present
and available.
