domain names should be enforced to start with a non-numeric character.
This used to be the case, but obviously got lost somewhere.

An alternative to re-instating the test would be to make it such that
the 'domain' parameter to commands is only interpretted as a domid iff a
lookup as a name fails. That would at least make things consistent, but
sometimes its just better to avoid the opportunity for confusion...
