Neither goredo, nor redo-c, not apenwarr/redo (as far as I remember)
explicitly tell how they behave with missing directories. So that can be
treated as an undefined behaviour. So portable .do-files just must not
rely on undefined behaviour. If someone explicitly expects for
directories to be created in his project, then he should explicitly
write that "mkdir -p" rule in his .do file and do not rely on some
undocumented sife-effects of some implementations (goredo). Portable and
correctly written .do files will behave the same way on all those three
implementations.
