Re: Re* [PATCH 2/4] refs: trim newline from reflog message

I think what deserves such a comment more is the prototype for
each_reflog_ent_fn describing what the parameters to that callback
function, to help the callers of the iterator what to expect.  That
is the end-user facing part.

Perhaps something along this line.

Subject: [PATCH] refs: document callback for reflog-ent iterators

refs_for_each_reflog_ent() and refs_for_each_reflog_ent_reverse()
functions take a callback function that gets called with the details
of each reflog entry.  Its parameters were not documented beyond
their names.  Elaborate a bit on each of them.
