Someone DID point that out.  I did in the very article which was cited in
Jim Crandall's article (which is cited above).  But this is just tradition;
there is no definitive syntax of Roman numerals.  All we have to go by are
examples actually found in authentic Roman works.  Who says a tool cannot
or should not do something untraditional as long as it is advertised as
doing so?  All are at liberty to modify my arabic.c to recognize only
Roman numerals of one type or another.
