So - after the "+0100" on the committer line, hd tells me (as

guess strchr will return NULL when "\0[HIA]....." is passed to it, and
segfault on the next iteration.

So - I am no closer to understanding what got me to this state, but
your reply was helpful anyway, thanks :-)

Well, it certainly seems like a bug in one of the history-rewriting
programs. Can you try rebasing, cherry-picking, etc on the original
version of the commit to see if you can reproduce the breakage?
