Thomas E. Dickey f6718d80c9 ncurses 5.6 - patch 20081011
+ update html documentation.
+ add -m and -s options to test/keynames.c and test/key_names.c to test
  the meta() function with keyname() or key_name(), respectively.
+ correct return value of key_name() on error; it is null.
+ document some unresolved issues for rpath and pthreads in TO-DO.
+ fix a missing prototype for ioctl() on OpenBSD in tset.c
+ add configure option --disable-tic-depends to make explicit whether
  tic library depends on ncurses/ncursesw library, amends change from
  20080823 (prompted by Debian #501421).
