Merging changelogs (again)

Hi all,

Pierre posted a Debian changelog-specific merger a couple of months ago.
Bryce just knocked another up from the Merge-o-matic source code not
knowing about Pierre's. You can find it at

  http://people.ubuntu.com/~bryce/scripts/merge_changelog

It's significantly longer, but I'm not sure how else it differs
as I haven't had chance to compare them in detail yet.

Bryce did say that he found this one handled epochs better than
Pierre's.

I can pass any feedback anyone has on.

Thanks,

James
