Never mind, Alexey V. Neyman pointed out that there are no square brackets
around the ``[(] pattern1) compound-list;;'' so at least one pattern needs to
be present. zsh and bash are simply more forgivig in this case, presumably
because there is no harm in doing so. But since empty case statements are
mostly useless the standard behavior that flags them makes more sense.
