[TxMt] Bug en Dup-line

[Juan Falgueras]

	I think I've find a bug in the duplicate line TM proc:

If you are in _the middle of_ a line with accented chars, dup-line  
(⌃⇧D)  do an strange thing sending the char besides the cursor to  
the dupped line:

   cout << "Estadística|" << endl;  (| indicates the cursor)  and  
press ⌃⇧D

makes

   cout << "Estadística << endl;
   cout << "Estadística"" << endl;

I don't know if this bug is already booked, my apologizes if so do.
