+1000 for Joel's idea of putting the ChangeLog entry in the commit

I rebase, cherry-pick, reorder and rewrite my commits very often, to
create patches for upstream submission and to organize my work before
pushing to the python branch. Every single time I do that, I have to
solve a conflict in a ChangeLog file. Not having to clean such mess
would definitely make my life simpler.

It's easy enough to collect the relevant changelog entries from the
commit messages when producing a patch for upstream.
