[PATCH v5 1/2] mergetool--lib: set IFS for difftool and mergetool

git-sh-setup sets IFS but it is not used by git-difftool--helper.
Set IFS in git-mergetool--lib so that the mergetool scriptlets,
diftool, and mergetool do not need to do so.

Add a winmerge scriptlet with the commands described in [1] so
that users can use winmerge without needing to perform any
additional configuration.

Changes since v4: we no longer need to worry about IFS since
it's already been set by patch 1/2.
