s/title line/title/ as you definitely do *not* want a line with a
title on it (and nothing else) in this context.

Ignoring of the '--date' may want to be eventually fixed, but for an
initial cut, using %as in the canned format is a good approach for
expediency.

I thought that %h can be told to give arbitrary long hash with
--abbrev=<n>, up to n==40 (or the number of bytes the hash of your
choice has), so I am not sure if `--no-abbrev-commit` is worth
mentioning.  I do not think I understand what you wanted to do by
using `--walk-reflogs` with the format at all, either.

Thanks.
