Details:

display () fails to display strings, structures, cells, etc as soon as they
contain the substring '<class '. For instance:


>> clear;  x.a = '<class '
x =

  scalar structure containing the fields:

    a = <class

>> display (x)
error: display: not defined for class "struct"
error: called from
    display at line 49 column 5


The problem occurs, for instance, when calling display () on a structure where
at least on field contains an object:


>> cd test/classes
>> clear;  x.a = SizeTester ([1 2])
x =

  scalar structure containing the fields:

    a = <class SizeTester>

>> display (x)
error: display: not defined for class "struct"
error: called from
    display at line 49 column 5
