Done.  To regenerate control manually, one has to run
"./debian/rules override_dh_testdir".

I also moved -examples to -doc.  Replaces+Breaks is not necessary
since no files are overwritten, but I added them anyway to facilitate
the removal of -examples.

AFAICS, what's left is to update debian/copyright and prepare the
changelog.  Do you want me take care of the latter?  I can also update
the copyright file, if it's OK to do it manually.
