seems I use a wrong number for the tree.
After pull, I got a three
1-2-3-4 local branch
 \5-6-7  remote
I hope to get
1-2-3-4 my local branch
Yes, I can get this by three hg co -m
hg co -C 2
hg co -m tip
hg co -C 3
hg co -m tip
hg co -C 4
hg co -m tip
but then 8,9,10 will be a merge verion, I can not export a single
changeset by hg export 8
I had to do
hg diff -r 8 -r7
hg diff -r 9 -r8
hg diff -r 10 -r9
General I won't push the changeset, just by export and send to others.
So I don't care there are multiheads, of cause, if there is a command
like hg hide 4
to hide the head, it will be better.

general I can use "hg export" and "combinediff",but that will lose description, 
if hg support, that will be better.

 Can this do what I describe above?
BTW, seems 0.6c doesn't support extension yet. I had to use the latest hg.
