Note that committing externals with a parent working copy sometimes works,
because some checks in the commit runner are not strict enough. (You can
check this behavior with depth empty; then pass the individual files you
like to commit.. All selected files and the common parent must be in the
same repository.)
At least this works with 1.4.x-1.6.x. And because depth is not infinity some
types of changes (e.g. deletes of directories) don't work.
