Given feedback on some of the comments, I truncated to the 80 character limit,
in code, (as opposed to function block comments). I have left a number of the
contentious comments as they are.

Another piece of feedback suggested using memset() instead of a loop to
initialise memory so I've added that change to the set.

I tried to respond to issues raised on the mailing list in the gmail web gui,
rather then in mutt. That was not a good idea and I don't think my comms got
through to the list. I know for future no web gmail.
