And it implies --all. Ah. I think it is a bit misnamed. Besides, --reflog options of pack-objects, show-branch and general revision-walk based programs are independent. I propose to change the behaviour of "--reflog" in revision.c (which should not have a big impact, since it is not even documented yet): - if --all-reflog is passed, include all reflogs (part of the current behaviour of --reflog), and - if --reflog is passed, write the reflog messages in addition to the commit lines, and rewrite the parent(s). > Rewriting the commits in memory to appear to have parents based > on their order of appearence in the reflog would nicely generate > a single strand of perls, but it makes it difficult to then access > the same commit's real parents, doesn't it?

Yes, but if we have to read the reflog anyway to determine the logical (local) parent, we can just as well read the message, and display it, too. What it buys us is that we do not duplicate efforts here, and we can easily visualize the reflog in gitk, too.
