the repository seems a mess for older commits

Hi X-symbol works in the 21.5 series only with an ancient patch from Steve Turnbull (2010). So I wanted to have a close look into the patch, which is against commit 9624523604c5. However hg log -G | grep 9624523604c5 Gives me, | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parent: 5036:9624523604c5 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parent: 5036:9624523604c5 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parent: 5036:9624523604c5 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parent: 5036:9624523604c5 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parent: 5036:9624523604c5 | o | | | | | | | | | | | | | | | | | | | | | | | | | | | changeset: 5036:9624523604c5 Which looks extremly messy. g log | grep 9624523604c5 parent: 5036:9624523604c5 parent: 5036:9624523604c5 parent: 5036:9624523604c5 parent: 5036:9624523604c5 parent: 5036:9624523604c5 changeset: 5036:9624523604c5 Which does not look much better. I bet this commit is pre mercurial. So two question: 1. That was still csv? 2. Which tool was used to convert to mercurial? I might ask on the mercurial list how to un spagetti this mess, maybe with rebase, but I would need some more information and then also would like to know whether there is interest in the list to do it.
