Bad grammar?  "hasn't been changed since 9f613dd", perhaps?

But more importantly, don't just give an abbreviated object name.  I
think "the comment hasn't changed since the for-each-ref command was
originally introduced" is what you meant to say, and it is OK to
append "since 9f613ddd (Add git-for-each-ref: helper for language
bindings, 2006-09-15)" to that sentence as a supporting material.

What change since 9f613dd do you have in mind, exactly, though?

I do not think the fact that this field indexes into used_atom[]
array has ever changed during the life of this implementation.
I see "static const char **used_atom;" in builtin/for-each-ref.c
still in the 'master', and that is the array that holds the atoms
that are used by the end-user request.

So I do not think "The comment was there from the beginning, it
described the initial implementation, the implementation was updated
and the comment has become stale" is a good justification for this
change, as I do not think that is what has happened here.

You may be changing used_atom to something else later in your
series, but then isn't that commit the appropriate place to update
this comment?
