Even if one would assume that /def/rules is not allowed to be
empty, having no nil-tag won't suffice, because it is
indecisable if a pattern will match or not, e.g. assume:

/foo/ -> bar

as only rule, it could be checked to be valid syntax and a valid
rule, though having this without a hardcoded default tag would
result in clients which get invisble for ever.
That's why a default nil-tag is necessary.
