Not sure I like the default 1.
I'm also a bit skeptical. Given the "shape" in mshape() I think it's
OK to make the user actually specify a shape.
What might be nice is to make mshape more clever, to automatically
determine the necessary number of columns c.
I'm not too keen on that either. The way mshape() works currently
there isn't a "necessary number of columns":

If X contains fewer than k = rc elements, the elements are repeated
cyclically; otherwise, if X has more elements, only the first k are
used.
