Aha, it's Cogito. cogito clone isn't fetching the tags (which is odd:
it's always done so for me with other repos, but that was pre-upgrade to
0.17.3 and pre-git-upgrade to 1.4.0). I wonder how to convince it to do

... aha, it parses git-ls-remote output and gets it wrong: tags from
git-ls-tags as of git-1.4.x don't have ^{} on their ends; in fact even
tracking back to 2005 I can't find a time when that was true, at least
according to the git documentation (and ^{} in that position has no
meaning to sed). Patch:

Strip no-longer-relevant trailing junk off the end of the tag transform.

 having a book review of an author for each letter in the alphabet.' -- rra
