Preliminary patch for testing

This patch takes care of the rejected format with a repeat in front of the DT
and the '/' inserted after.  I am still testing and exploring the business with
the USE statement.

Note: I have not checked to make sure the runtime also handles the repeat
correctly.  This is a work in progress. I am suspicious of this patch since I
expected the unget_char to be sufficient and the lexing would cycle around and
catch that '/'. Obviously it does not, but I do want to understand why not. I
do understand why the repeat digit was missed and that part is good. (Helps if
you put the new code in the right place, ;) )
