Re: texinfo4.5.91: problems with CSS inclusion

    At the end of append_char() in html.c
    the variable buf->length should be increased by one.

Ain't it the truth :).  Thanks for finding my silly mistake.  How about this:

*** html.c	13 May 2003 21:07:55 -0000	1.16
--- html.c	18 May 2003 13:14:29 -0000	1.17

      buffer_type *buf;
      int c;
  {
!   char str[2] = { 0, 0 };
!   str[0] = c;  /* appease SGI compiler */
! 
!   if (buf->length + 1 >= buf->size)
      {
        buf->size += 100;
        buf->buffer = xrealloc (buf->buffer, buf->size);
-       buf->buffer[buf->length] = 0;  /* in case it was the first alloc */
      }
!   strcat (buf->buffer, str);
  }
