Revision 2277

Reformatted the FUNCTION_CMP subroutine to make it more readable. Also,
one functional change:

< (defined ($inputs_ref->{$prev_ans_label} and $inputs_ref->{$prev_ans_label} =~/\S/) )
> (defined $inputs_ref->{$prev_ans_label} and $inputs_ref->{$prev_ans_label} =~/\S/)

I think the latter was what was intended.
