  22  * - Need to document error code meanings.
  23  * - Need to do something with \* on destinations.
  24  * - Make the parameter a long?
  25  *
  26  * reader.c - RTF file reader.  Release 1.10.
  27  *
  28  * ASCII 10 (\n) and 13 (\r) are ignored and silently discarded.
  29  * Nulls are also discarded.

  35  *
  36  * 19 Mar 93
  37  * - Add hack to skip "{\*\keycode ... }" group in stylesheet.
  38  * This is probably the wrong thing to do, but it's simple.
  39  * 13 Jul 93
  40  * - Add THINK C awareness to malloc() declaration.  Necessary so
  41  * compiler knows the malloc argument is 4 bytes.  Ugh.
  42  * 07 Sep 93
  43  * - Text characters are mapped onto standard codes, which are placed
  44  * in rtfMinor.
  45  * - Eliminated use of index() function.
  46  * 05 Mar 94
  47  * - Added zillions of new symbols (those defined in RTF spec 1.2).
  48  * 14 Mar 94
  49  * - Public functions RTFMsg() and RTFPanic() now take variable arguments.
  50  * This means RTFPanic() now is used in place of what was formerly the
  51  * internal function Error().
  52  * - 8-bit characters are now legal, so they're not converted to \'xx
  53  * hex char representation now.
  54  * 01 Apr 94
  55  * - Added public variables rtfLineNum and rtfLinePos.
  56  * - #include string.h or strings.h, avoiding strncmp() problem where
  57  * last argument is treated as zero when prototype isn't available.
  58  * 04 Apr 94
  59  * - Treat style numbers 222 and 0 properly as "no style" and "normal".
