Thomas E. Dickey 34d602f272 ncurses 5.9 - patch 20140524 
+ fix typo in ncurses manpage for the NCURSES_NO_MAGIC_COOKIE
  environment variable.
+ improve discussion of input-echoing in curs_getch.3x
+ clarify discussion in curs_addch.3x of wrapping.
+ modify parametrized.h to make fln non-padded.
+ correct several entries which had termcap-style padding used in
  terminfo: adm21, aj510, alto-h19, att605-pc, x820 -TD
+ correct syntax for padding in some entries: dg211, h19 -TD
+ correct ti924-8 which had confused padding versus octal escapes -TD
+ correct padding in sbi entry -TD
+ fix an old bug in the termcap emulation; "%i" was ignored in tparm()
  because the parameters to be incremented were already on the internal
  stack (report by Corinna Vinschen).
+ modify tic's "-c" option to take into account the "-C" option to
  activate additional checks which compare the results from running
  tparm() on the terminfo expressions versus the translated termcap
  expressions.
+ modify tic to allow it to read from FIFOs (report by Matthieu Fronton,
  cf: 20120324).
> patches by Nicolas Boulenguez:
+ explicit dereferences to suppress some style warnings.
+ when c_varargs_to_ada.c includes its header, use double quotes
  instead of <>.
+ samples/ncurses2-util.adb:  removed unused with clause.  The warning
  was removed by an obsolete pragma.
+ replaced Unreferenced pragmas with Warnings (Off).  The latter,
  available with older GNATs, needs no configure test.  This also
  replaces 3 untested Unreferenced pragmas.
+ simplified To_C usage in trace handling.  Using two parameters allows
  some basic formatting, and avoids a warning about security with some
  compiler flags.
+ for generated Ada sources, replace many snippets with one pure
  package.
+ removed C_Chtype and its conversions.
+ removed C_AttrType and its conversions.
+ removed conversions between int, Item_Option_Set, Menu_Option_Set.
+ removed int, Field_Option_Set, Item_Option_Set conversions.
+ removed C_TraceType, Attribute_Option_Set conversions.
+ replaced C.int with direct use of Eti_Error, now enumerated.  As it
  was used in a case statement, values were tested by the Ada compiler
  to be consecutive anyway.
+ src/Makefile.in: remove duplicate stanza
+ only consider using a project for shared libraries.
+ style. Silent gnat-4.9 warning about misplaced "then".
+ generate shared library project to honor ADAFLAGS, LDFLAGS.
