sergefp@mysql.com da332aca40 Fix for BUG#6825: When calculating Item_func_neg::max_length, add 1 for '-'. ...

For numeric constants we only need to add, since the parser doesn't produce 
negative numbers. 
For strings we only add (we actually could substract 1 if given string is a constant 
and it has '-number' form but we're not doing that because 
 * we set max_length bigger then necessary in other cases as well.  
 * the current solution is simpler and safer (bigger max_length is better then cutting out)
