output from bnfsunit

[Brett Tangedal <tangedal@mathmac.cofc.edu>]

I have a minor complaint about the way bnfsunit[5][2]
is displayed. I've gotten answers like

Mat(4)

or

[2, 0; 0, 2]

when what I expect from the usual Pari protocol for the cyclic
components of an abelian group is [4] and [2,2] respectively.
I'd like to suggest that the usual Pari protocol be implemented
here for the sake of uniformity and ease of use.

P.S. I'm presently using Version 2.1.3
