Oops, yes.  I should have realized it must be the difference between
having CR and not.  It's not obvious without looking at the code whether
there's a way to turn that off with an MCA configuration variable.

Oh, yes.  I really wasn't awake yesterday.  I was confused initially by
it ignoring empty fields, but I'm not a perl expert.  It's no big
problem for me, anyhow.  I can have a look sometime and see if I can
find a clean way round it.
