I think the most natural expectation is for the output from the
"archive --recurse-submodules" command is to be logical
concatenation of "archive" run at the top-level and submodules,
adjusting the output from the latter with leading paths to the
submodules.  For that to happen, the attributes that apply to paths
inside a submodule must come from that submodule's setting.
