we used to NUL terminate explicitly.

christos 27916d7c22 PR/51517: Jay West: Tty settings not restored on exit 
PR/51518: Jay West: prompt is interleaved with client output

Both these issues are caused by rl_restore_handler not DTRT; fix
it so that it kills the internal libedit state completely. This is
inefficient, but it works.

Also fix:
1. add append_history()/H_NSAVE_FP
2. call the rl_startup_hook before printing the first prompt as documented.
   callint it from rl_initialize breaks python, because the callback ends
   up being invoked before the readline module is installed, and we end up
   dereferencing a NULL pointer.
3. add el_resize_terminal.

With those changes, s/lreadline/ledit/g in python works.

christos 469d44f8e7 Get rid of private/public; keep protected (Ingo Schwarze) 2016-04-11 18:56:31 +00:00
christos a75ea7b9c4 chartype cleanups from Ingo Schwarze: 
- The file tokenizer.c no longer uses chartype.h,
   so don't include the header.

 - The dummy definitions of ct_{de,en}code_string() for the
   NARROWCHAR case are only used in history.c, so move them there.

 - Now the whole content of chartype.h is for the wide character
   case only.  So remove the NARROWCHAR ifdef and include the
   header only in the wide character case.

 - In chartype.h, move ct_encode_char() below the comment explaining it.

 - No more need for underscores before ct_{de,en}code_string().

 - Make the conversion buffer resize functions private.
   They are only called from the decoding and encoding functions
   inside chartype.c, and no need can possibly arise to call them
   from anywhere else.
