This is also what add_reflog_for_walk() does, but that function tries to resolve
the argv[i] part first, without doing the dwim_log().

Perhaps we can also ...

Sorry, I do not understand what you meant by the above comment.

 - "This is also what add_reflog_for_walk() does" -- I take it you mean
   the use of dwim_log() instead of dwim_ref()?

 - "... but that function tries to resolve the argv[i] part first" -- do
   you mean the resolve_ref("HEAD"...) call inside "if (!*branch)"
   codepath?

   That one serves different purposes than "delete HEAD@{42}".  It is
   about showing "@{42}" --- in order to show reflog for "the current
   branch", it figures out the current branch by resolving "HEAD".

In any case, what confuses me is I cannot tell if you do or do not have
issues that I did not think of with the "s/dwim_ref/dwim_log/" change.
Are you saying "no that cannot be a correct fix; see the way dwim_log() is
used in add_reflog_for_walk() -- it does more than your one-liner"?

By the way, I think the idea of "Perhaps we can also..." part is good.
