Dear Users,

1. StringFill[] specification about negative 3rd argument case is changed.
  CAUTION: This change is backword incompatible with V1.0.10.4.4a31 - V1.0.10.4.4a41.

    * Formal specification of ``OLD'' StringFill[](Revision 1.97: V1.0.10.4.4a31)
     StringFill[s1_String, s2_String, len_Real] := Which[
       len  > 0, StringJoin[s1, s2, s2, ..., s2][ 1,  Abs[len]],
       len == 0, "",
       len  < 0, With[{l1 = Min[StringLength[s1], Abs[len]]},
         StringJoin[StringFill[s2, s2, Abs[len] - l1], s1[1, l1]]]];

    * Formal specification of ``NEW'' StringFill[](This update: V1.0.10.4.4a43)
     StringFill[s1_String, s2_String, len_Real] := Which[
       len  > 0, StringJoin[s1, s2, s2, ..., s2][ 1,  Abs[len]],
       len == 0, "",
       len  < 0, StringJoin[s2, s2, ..., s2, s1][-Abs[len], -1]];

  Examples:
    StringFill["abcd", "123", -10] returns "123123abcd"
    StringFill["abcd", "123",  -9] returns "23123abcd"
    StringFill["abcd", "123",  -8] returns "3123abcd"
    StringFill["abcd", "123",  -7] returns "123abcd"
    StringFill["abcd", "123",  -6] returns "23abcd"
    StringFill["abcd", "123",  -5] returns "3abcd"
    StringFill["abcd", "123",  -4] returns "abcd"
    StringFill["abcd", "123",  -3] returns "bcd"
    StringFill["abcd", "123",  -2] returns "cd"
    StringFill["abcd", "123",  -1] returns "d"
    StringFill["abcd", "123",   0] returns ""
    StringFill["abcd", "123",   1] returns "a"
    StringFill["abcd", "123",   2] returns "ab"
    StringFill["abcd", "123",   3] returns "abc"
    StringFill["abcd", "123",   4] returns "abcd"
    StringFill["abcd", "123",   5] returns "abcd1"
    StringFill["abcd", "123",   6] returns "abcd12"
    StringFill["abcd", "123",   7] returns "abcd123"
    StringFill["abcd", "123",   8] returns "abcd1231"
    StringFill["abcd", "123",   9] returns "abcd12312"
    StringFill["abcd", "123",  10] returns "abcd123123"
