Thanks, but I don't think that is right.  It assumes the header line is 
space-delimited (or at least that spaces get converted to tabs).  We have 
not specified the format of the header line, and it cannot usefully be 
fixed format.  So I think we need to specify it is delimited by 'sep'
(not tab).
