Comment:

 Thanks for this fix!

 Here's what I would change before merging it:
 * rebase on the latest master
   * that is, cherry pick afbda70 onto master, removing dbbd36e and b5b8d62
 - these are merge and fix commits that aren't relevant to the patch
 * keep the newline that's removed from the end of addressmap.c
 * add the smallest network size to the manpage, with a note that larger
 sizes are better :-)
