ncurses 6.0 - patch 20161015

+ amend internal use of tputs to consistently use the number of lines
  affected, e.g., for insert/delete character operations.  While

  "*" proportional delay for these operations, prompting a change in
  doupdate.
+ regenerate llib-* files.
+ regenerate HTML manpages.
+ fix several formatting issues with manual pages.
