OK.  As .gitattributes is tracked just like .gitmodules in tree, the
project can adjust the path pattern that matches a renamed submodule
and gives it an attribute in .gitattributes in the same commit in
the superproject that moves the directory to which the submodule is
bound, just like it updates .gitmodules to adjust the name<->path
mapping.  So that plan solves my specific worry about using "path"
for grouping and not "name".

Thanks.
