Understood!  Also, I understood you to say that there are differences in the way protected macros are treated within file-name specs by different primitives, and maybe also for the same (name) primitive on different engines.  Is that corr3ct?

Maybe not to the spaces question, but maybe it is quite important in a more general sense?

If the handling of “tex input intended to specify a file name” may be treated differently by different “file-name processing primitives” or by the same (name) primitive in different engines then that is surely of some import.  At least these facts should be clearly established and fully documented.
