ncurses 5.9 - patch 20110910

ncurses 5.9 - patch 20110910

+ modify misc/gen_edit.sh to select a "linux" entry which works with
  the current kernel rather than assuming it is always "linux3.0"
  (cf: 20110716).
+ revert a change to getmouse() which had the undesirable side-effect
  of suppressing button-release events (report by Damien Guibouret,
  cf: 20100102).
+ add xterm+kbs fragment from xterm #272 -TD
+ add configure option --with-pkg-config-libdir to provide control over
  the actual directory into which pc-files are installed, do not use
  the pkg-config environment variables (discussion with Frederic L W
  Meunier).
+ add link to mailing-list archive in announce.html.in, as done in
  FAQ (prompted by question by Andrius Bentkus).
+ improve manpage install by adjusting the "#include" examples to
  show the ncurses-subdirectory used when --disable-overwrite option
  is used.
+ install an alias for "curses" to the ncurses manpage, tied to the
  --with-curses-h configure option (suggested by Reuben Thomas).
