ncurses 5.9 - patch 20111015

+ improve description of --disable-tic-depends option to make it
  clear that it may be useful whether or not the --with-termlib
  option is also given (report by Sven Joachim).
+ amend termcap equivalent for set_pglen_inch to use the X/Open
  "YI" rather than the obsolete Solaris 2.5 "sL" (cf: 990109).
+ improve manpage for tgetent differences from termcap library.
