Run "hg bisect -h".  It's a method to track down the regression point
during changesets.  A brief instruction is below:

- First, initizliaze
	% hg bisect init
- Go to the broken point (usually the latest changeset, tip)
	% hg update -rtip
- Mark it as bad
	% hg bisect bad
- Go to the changeset that is known to work (e.g. v1.0.15)
	% hg update -rv1.0.15
- Mark it as good
	% hg bisect good
  then the bisect will move to a next changeset to try.
- Try this changeset, and mark either good or bad.
- Repeat until the problematic changeset is found.
- Reset bisect
	% hg bisect reset

Note that when you need an additonal patch, you have to apply the
patch at each time, and revert it (hg revert --all) before marking
good/bad.
