reflog delete results in reflog show strangeness?

I see a possible bug in the output of 'git reflog show' after using
'git reflog delete'.  Simple example:

$ git init
$ git commit --allow-empty -m 'root'
$ git commit --allow-empty -m 'good'
$ git commit --allow-empty -m 'bad'
$ git reflog
996ca67... HEAD@{0}: commit: bad
e431a20... HEAD@{1}: commit: good
992dd88... HEAD@{2}: commit (initial): root

$ git reset HEAD^
$ git reflog
e431a20... HEAD@{0}: HEAD^: updating HEAD
996ca67... HEAD@{1}: commit: bad
e431a20... HEAD@{2}: commit: good
992dd88... HEAD@{3}: commit (initial): root

$ git reflog delete HEAD@{1}
$ git reflog
e431a20... HEAD@{0}: HEAD^: updating HEAD
996ca67... HEAD@{1}: commit: good
992dd88... HEAD@{2}: commit (initial): root

In this listing, please note that, after the delete, the commit SHA
shown as HEAD@{1} is that of the deleted reference (the bad commit)
and does not match the reflog message, which has the expected value.

Thank you,
