This should be squashed into the patch that introduces the
interpret-trailers command, IMHO (or if it should be reviewed
separately, it can be an earlier patch).  That way, someone looking at
when the command was introduced and wanting to understand what it was
originally meant to do has the information close by.

Thanks for picking up the 'git commit --fixes' topic and your steady
work improving the series.

Do you have an example?  Does it work like this?

	$ git interpret-trailers 'signoff=Jonathan Nieder <jrnieder@gmail.com>' <<EOF
	> foo bar baz qux
	> EOF
	foo bar baz qux

	Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>
	$

A short EXAMPLES section could help.

If I am understanding it correctly, would a name like 'git add-trailers'
work?  How do I read back the trailers later?

Why support both '=' and ':'?  Using just one would make it easier to
grep through scripts to see who is adding signoffs.

Hope that helps,
