   2  * - Need to document error code meanings.
   3  * - Need to do something with \* on destinations.
   4  * - Make the parameter a long?
   5  *
   6  * reader.c - RTF file reader.  Release 1.10.
   7  *
   8  * ASCII 10 (\n) and 13 (\r) are ignored and silently discarded.
   9  * Nulls are also discarded.
  10  * (although the read hook will still get a look at them.)
  11  *
  12  * "\:" is not a ":", it's a control symbol.  But some versions of
  13  * Word seem to write "\:" for ":".  This reader treats "\:" as a
  14  * plain text ":"
  15  *
  16  * 19 Mar 93
  17  * - Add hack to skip "{\*\keycode ... }" group in stylesheet.
  18  * This is probably the wrong thing to do, but it's simple.
  19  * 13 Jul 93
  20  * - Add THINK C awareness to malloc() declaration.  Necessary so
  21  * compiler knows the malloc argument is 4 bytes.  Ugh.
  22  * 07 Sep 93
  23  * - Text characters are mapped onto standard codes, which are placed
  24  * in rtfMinor.
  25  * - Eliminated use of index() function.
  26  * 05 Mar 94
  27  * - Added zillions of new symbols (those defined in RTF spec 1.2).
  28  * 14 Mar 94
  29  * - Public functions RTFMsg() and RTFPanic() now take variable arguments.
  30  * This means RTFPanic() now is used in place of what was formerly the
  31  * internal function Error().
  32  * - 8-bit characters are now legal, so they're not converted to \'xx
  33  * hex char representation now.
  34  * 01 Apr 94
  35  * - Added public variables rtfLineNum and rtfLinePos.
  36  * - #include string.h or strings.h, avoiding strncmp() problem where
  37  * last argument is treated as zero when prototype isn't available.
  38  * 04 Apr 94
  39  * - Treat style numbers 222 and 0 properly as "no style" and "normal".
