ISERROR(undefinedname) behavior

[Eike Rathke <erack@sun.com>]

Hi,

There is a special case with the ISERROR function when used with an
undefined name, as in =ISERROR(undefinedname)

Excel and Gnumeric return TRUE, while Calc returns a #NAME? error
because the error is already propagated at compile time when
encountering 'undefinedname' and the formula is never interpreted.
Kspread 1.5.0 returns FALSE, which obviously is wrong.

Do we want to require that ISERROR still returns TRUE in this case?
