* truncate field contents to field length if field is or becomes static

Browse Source 
* Allow field options to be changed when field posted unless field
   is the current one.
 * Allow field justification to be changed when field posted unless it
   is the current one.
 * dynamic_field_info now returns field size in rows and columns if
   the field is static - previously this was an error.
