  Log Message:
  -----------
  Do not use :: in IPv6 addresses without zero-collapsing

Addresses that do not contain a sequence of two or more zero-words should
not contain the zero-collapse marker (::).  Rather than adding a special
case in the output generation code for this, this patch adds a branch to
a code block that simply outputs 8 words, separated by ':'.

The testcase has been expanded to contain at least one of each possible
case: leading collapsible zero-words, collapsible zero-words in the middle,
trailing collapsible zero-words, addresses without zero-words.
