Re: [Nmh-workers] troff 4 column output [OT]

Best off asking on the GNU groff mailing list, even if you're not using
groff but an alternative, e.g. Heirloom troff.  That's where us troffers
hang out, and a friendly bunch we are too.

MC and MULN?  MULN isn't for MC but MULB,MULN...,MULE.  Here's four
columns with MC.

    $ (printf '.nf\nfoo\n.ll 5i\n.MC 1i\n' &&

                                       ‐ 1 ‐
           foo
           1          11        21         31
           2          12        22         32
           3          13        23         33
           4          14        24         34
           5          15        25         35
           6          16        26         36
           7          17        27         37
           8          18        28         38
           9          19        29         39
           10         20        30
           bar
    $
