The point is that (as per the other message), this branch is now *the*
project.  Making an arbitrary cut in history at any point in time (Feb
2008 in this case) makes no sense.

I simply don't like idea of dumping away the whole line of development
with the project's early history.  If we're going to leave some
history aside, I'd rather drop Feb-May 2008 than the previous years.
If we can't make this work, I'll apply the recent changes as a single,
gigantic change with a huge commit message (the whole log), and refer
to the other branch for details.

If I have to choose between 3 months and 3 years of history, I lose
the three months, not the three years. Period.

bzr graft would do the job, we'll see if I can make it run.

Cheers,
