mksh does not allow $COLUMNS to be set below 12. Quoting mksh(1)
$COLUMNS is "always set, defaults to 80, unless the value as reported
by stty(1) is non-zero and sane enough". This applies also to setting
it directly for one command:
$ COLUMNS=30 python -c 'import os; print os.environ["COLUMNS"]'
30
$ COLUMNS=20 python -c 'import os; print os.environ["COLUMNS"]'
20
$ COLUMNS=10 python -c 'import os; print os.environ["COLUMNS"]'

I wonder if this is an easier workaround, though.
env COLUMNS=10 $cmd
In any case, I'd split this patch to three, as these tests belong to two
independent topics.
Hi Junio, Zbigniew.

It works for me:
$ mksh -c 'COLUMNS=10 env | grep COLUMNS'
COLUMNS=113
$ mksh -c 'env COLUMNS=10 env | grep COLUMNS'
COLUMNS=10
$ dpkg -l mksh

This approach with 'env COLUMNS=1 git ...' looks nicer, and works when
invoked directly, but doesn't work when run under the test harness,
because bin-wrappers/git uses !/bin/sh, which resets COLUMNS. So this
simpler approach doesn't look feasible.
