[Merge] ~bryce/ubuntu-dev-tools:update-maintainer-recursive into ubuntu-dev-tools:master

[Bryce Harrington]

Thank you for the review mapreri.

That's a good point, as a user might have a ~/debian/ directory for their debian work.  I've adjusted the code to include your recommendation.

stirling:~/ubuntu/Dovecot/dovecot-gu$ mkdir ~/debian
stirling:~/ubuntu/Dovecot/dovecot-gu$ update-maintainer
The package targets Debian. Doing nothing.
stirling:~/ubuntu/Dovecot/dovecot-gu$ mv debian/ debian-foo
stirling:~/ubuntu/Dovecot/dovecot-gu$ update-maintainer
No control file found in ./debian.
