Thanks for telling us.

Since your situation is very special, and since vc-hg-root-log-format
is a defcustom, I think for you to customize the value to make it work
in your setup is exactly the right solution of this problem.  So I'm
closing this bug report, as I think nothing has to be done for it in
Emacs core.
