The name here must match the name you sign the patch off as,
i.e. this line should read

There should be a mention of the commit that added the hook, namely,
8089c85b (git-commit: add a prepare-commit-msg hook, 2008-02-05).
The log message for this patch should also observe that this third
argument, which is given only when the source is 'commit', was not
mentioned in the sample hook added by the original commit.
Interestingly, its log message reads:
...
Its purpose is to modify the commit message in-place.
It takes one to three parameters. The first is the name of the file that
the commit log message. The second is the source of the commit message,
and can be: "message" (if a -m or -F option was given); "template" (if a
-t option was given or the configuration option commit.template is set);
"merge" (if the commit is a merge or a .git/MERGE_MSG file exists);
"squash" (if a .git/SQUASH_MSG file exists); or "commit", followed by
a commit SHA1 as the third parameter (if a -c, -C or --amend option
was given).
...
So it wasn't a mistake that the sample did not mention it. I think
the reason why the original, and today's version, does not mention
it is because no sample code in the file actually uses it.
I am not yet convinced that it is a good idea to only add mention to
the third one if we are not showing how it is used to this file,
especially given that in the documentation we _do_ cover these
arguments fully.
Thanks.
