ncurses 5.9 - patch 20150418

+ avoid a blank line in output from tabs program by ending it with
  a carriage return as done in FreeBSD (patch by James Clarke).
+ build-fix for the "--enable-ext-putwin" feature when not using
  wide characters (report by Werner Fink).
+ modify autoconf macros to use scripting improvement from xterm.
+ add -brtl option to compiler options on AIX 5-7, needed to link
  with the shared libraries.
+ add --with-extra-suffix option to help with installing nonconflicting
  ncurses6 packages, e.g., avoiding header- and library-conflicts.
  NOTE: as a side-effect, this renames
	  adacurses-config to adacurses5-config and
	  adacursesw-config to adacursesw5-config
+ modify debian/rules test package to suffix programs with "6".
+ clarify in curs_inopts.3x that window-specific settings do not
  inherit into new windows.
