Re: [Nmh-workers] sortm's Default of all is Brain-Damaged.

[Paul Fox]

i've recreated your test case, and the '-limit 0' test still gives
reverse date sort:
    $ s
    1  Thu, 03 Oct 2012 00:12:00 +0000  A
    2  Thu, 02 Oct 2012 00:12:00 +0000  A
    3  Thu, 02 Oct 2012 00:12:00 +0000  C
    4  Thu, 01 Oct 2012 00:12:00 +0000  B
    5  Thu, 01 Oct 2012 00:12:00 +0000  A
    $ sortm -textf subject -limit 0
    $ s
    1  Thu, 03 Oct 2012 00:12:00 +0000  A
    2  Thu, 02 Oct 2012 00:12:00 +0000  A
    3  Thu, 01 Oct 2012 00:12:00 +0000  A
    4  Thu, 01 Oct 2012 00:12:00 +0000  B
    5  Thu, 02 Oct 2012 00:12:00 +0000  C

so that's odd.
