No problem. :)

And to ridgerunner: After mentioning this irregularity to Dominic Sayers, he mentioned that RFC 5321 probably took into account (the unpublished) RFC 5952, which is an update to 4291 and states in section 4.2.2 that 'the symbol "::" MUST NOT be used to shorten just one 16-bit 0 field. For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but 2001:db8::1:1:1:1:1 is not correct.'
