Fix parsing web commits from ipv6 addresses.

I weakended the regexp, so this matches ipv6 addresses too. It does not
ensure that the address is valid, but that should not matter here.

Note that addresses ending in "::" are not matched, so eg, the unspecified
address will not match -- but should never appear here anyway.
