Re: Lua code formatters and beautifiers

This patch in llex.c no longer drops characters in comments:

$ diff llex.c,orig llex.c

<           luaZ_resetbuffer(ls->buff);  /* 'skip_sep' may dirty the buffer */
450c449

<         break;

As before, the patched code returns 'C' for a long comment and 'c' for a short
comment, with the contents of the comment in seminfo->ts.
 
Again, adding support for this in ltokenp is just adding two lines in proxy.c:
    switch (t)
    {
      case 'C':
      case 'c':
      case TK_STRING:
      case TK_NAME:
       lua_pushstring(L,getstr(seminfo->ts));
       break;
       ...

All feedback welcome.
