Follow-up Comment #5, bug #51412 (project octave):
In addition I think we need to be wary about the definitions of "string" and
"cell string" in this function, and places where string_value and
cellstr_value are used to compare two operands.
The is_string and iscellstr tests return true for values that cannot be
exactly represented by our normal definition of what a "string" is.
Simple example of a two-dimensional character matrix:
>> a = ['aaa'; 'bbb'];
>> string_value (a)
ans = aaa
>> cellstr_value (a)
ans =
{
[1,1] = aaa
}
The string_value method truncates a multi-dimensional character vector to
return just the first row (this has been discussed in other bug reports). The
cellstr_value method calls string_value.
