Bug#37301 Length and Max_length differ with no obvious reason(2nd version)
Length value is the length of the field,
Max_length is the length of the field value.
So Max_length can not be more than Length.
The fix: fixed calculation of the Item_empty_string item length
(Patch applied and queued on demand of Trudy/Davi.)
