Hi Holger

Thanks for having a look and suggesting that additional extension!

ah, I'd not seen one of these in action. I should go find some additional buildinfo files to 
play with.

Something like:

In [1]: from debian import deb822
In [2]: info = deb822.BuildInfo(open("debian/tests/test_BuildInfo"))
In [3]: changes = info.get_changelog()

where changes is a debian.changelog.ChangeLog object containing 1 ChangeBlock. 

https://python-debian-team.pages.debian.net/python-debian/api/
debian.changelog.html#debian.changelog.Changelog

Thinking about the steps:

* If there is no Binary-Only-Changes field, it would just return None

* It would first remove the initial space indent and dots, raising a ValueError if they 
weren't there.

* Creating the ChangeBlock object might raise debian.changelog.ChangelogParseError or 
debian.changelog.VersionError should the changelog be bad in some way.

Like the accessors for environment and Installed-Build-Depends, this would be a read-
only method, not providing a simple way to edit/insert the changelog into an existing 
buildinfo file.

Is that what you imagined?

cheers
Stuart
