I think that is most recent which can I get with 
--8<---------------cut here---------------start------------->8---
hg clone http://hg.rename-it.nl/pigeonhole-0.3-sieve-extprograms/
--8<---------------cut here---------------end--------------->8---

If I understand hg commands "hg branches -v"   gives me: 
--8<---------------cut here---------------start------------->8---
default                       47:3bd6ed27ae26
