How about this instead?  Except perhaps with a commit message that is vaguely
understandable?

If we encounter an address part shaped like "[HOST]:PORT", we skip the opening
bracket and replace the closing one with a NUL.  The variable host then points
to HOST and we've cut off the PORT part.  Thus, when we go looking for it using
host a bit later, we can't find it.  Start at end instead, which either points
to the colon, if present, or is equal to host.

We have similar code in daemon.c.  Can we share more?  And make it testable?
