Sync byobu 5.3-1 (main) from Debian unstable (main)

From what I can see on a quick review is that:
 - the .pot file magic is not run in the Debian package
 - and a few files are installed differently:

daniel@daydream:~$ debdiff byobu_5.3-*deb pbuilder/precise_result/byobu_5.3*deb
[The following lists of changes regard files as different if they have
different names, permissions or owners.]

Files in second .deb but not in first
-------------------------------------
-rw-r--r-- root/root /usr/share/byobu/keybindings/common
-rwxr-xr-x root/root /etc/profile.d/Z97-byobu.sh

Files in first .deb but not in second
-------------------------------------
-rw-r--r-- root/root /etc/profile.d/Z97-byobu.sh

Dustin: can you have a look at this?

Daniel, thanks.

Alexander, thanks for caring for the Debian byobu package.

In this case, Debian's byobu package is downstream from Ubuntu, as I'm both the upstream byobu maintainer and the Ubuntu byobu package maintainer.

I'll gladly take packaging fixes and improvements into lp:byobu and release a new byobu. Please just attach bzr branches or debdiffs/patches to bugs.launchpad.net/byobu and I'll handle them.

Well, the only thing I see here that I don't really like is the hard dependency on debhelper 7.

When I release Byobu, I automatically push source packages to the ppa:byobu/ppa, and build for all supported Ubuntu releases, back to 8.04 hardy, which doesn't have debhelper 7.

I'll try to copy over dh7 from backports.

This bug was fixed in the package byobu - 5.4-0ubuntu1

---------------
byobu (5.4-0ubuntu1) precise; urgency=low

  [ Alexander Chernyakhovsky and Dustin Kirkland ]
  * === added directory debian/source, debian/control, debian/install,
    debian/rules, debian/source/format: LP: #917682
    - switch to dh7 format for build

  [ Dustin Kirkland ]
  * debian/install, debian/links, === removed symlink
    usr/share/byobu/keybindings/common, === target was uf-keys,
    usr/share/byobu/keybindings/common:
    - re-establish a symlink for the icon/art; note, this should
      really be handled in the autohell build for portability;
      using debian/links is hacky
    - drop common as a link; instead, use "source"
