Would it be possible to remove of the double quotes in the daterange display of BC dates?

select '[0001-10-29 BC,2011-10-29)'::daterange;
daterange
------------------------------
["0001-10-29 BC",2011-10-29)
(1 row)

after all, it's also:

select '0001-10-29 BC'::date;
date
---------------
0001-10-29 BC
(1 row)

without double quotes. It's not important, perhaps; it just looks ugly to me.

Do they serve a purpose?
