Another thing to keep in mind is that we need to ensure that we give
a good way for these third-party tools to integrate well with the
core Git tools to form a single toolchest for the users.  I would
love to be able to do

    $ (cd git.git && make install)
    $ (cd git-imerge.git && make install)

and then say "git imerge", "git --help imerge", etc.  The same for
the remote helpers that we may be splitting out of my tree into
their own stand-alone projects.

I _think_ it probably is OK for git-imerge.git/Makefile to peek into
our Makefile, e.g.

    $ cd git-imerge.git
    $ make GIT_SOURCE_DIR=../git.git install

to learn where imerge should install its subcommand implementation
and documentation.  It might even want to borrow the test framework
by using $GIT_SOURCE_DIR/t/test-lib.sh or somesuch.  There may be
some changes the third-party tool authors would want to have in our
Makefile to help them better when building their tools this way; I
dunno.

I also think that there should be a way to make it really easy to
install these third-party tools to augment the installed version of
Git without having the source tree of Git.  We have ways for them to
ask us where things are expected to be, e.g.

    $ git --html-path
    $ git --man-path
    $ git --exec-path

but I am not sure if these are enough, or if it would help them to
add a bit more, then what these "a bit more" are.
