Follow-up Comment #2, bug #56363 (project pspp):
Regarding the Autorecode failures, When I look at those tests,
I'm not sure whether the expected results are in fact correct (whatever
They seem to be expecting that string values which are all whitespace have the
same value semantics. So for example, the string " " will group identically
to the string " ".
I wrote those tests many years ago, and I suspect I checked it
against a version of spss which I had access to at that time.
I just wish I'd put a comment about it there.
If someone has access to spss it would be great if it could be retested. If
it does turn out that " " and " " are
to be treated as identical, the we should make special provision for this in
the functions value_equal, value_compare_3way and value_hash.
