In fcl-passrc, TPasElement.GetDeclaration does not display the length of short strings

As in title. For example, the declarations in the following program:

unit test;
{$mode objfpc}{$H+}

interface

var
  X : string[10];

type
  Tx = string[5];

implementation

end.

are shown as follows:

X : string
Tx = string
