When the --objects argument is given to rev-list, an argument of the
form "^$tree" can be given to exclude all blobs and trees reachable from
that tree, but an argument of the form "^$commit" only excludes that
commit, not any blob or tree reachable from it. Make "^$commit" behave
consistent to "^$tree".
Also, formalize this behavior in unit tests. (Some of the added tests
would already pass even before this commit, but are included
nevertheless for completeness.)
