config-package-dev oneiric SRU metabug

[Impact]
config-package-dev 4.13 in precise fixes three issues found while testing config-package-dev 4.12 on oneiric:

• Because of an incompatible Perl 5.12 change that broke the ‘encode’ script, all config packages built with config-package-dev now conflict with each other.
• DEB_CHECK_FILES and DEB_TRANSFORM_FILES cannot find dpkg’s md5sums for files in Multi-Arch: same packages.
• dpkg and dpkg-divert may write localized output on non-English locales, which breaks parsing.

[Development Fix]
config-package-dev 4.13 has been in precise for 3 weeks. It has also been tested on all Ubuntu releases as part of Debathena <http://debathena.mit.edu/>.

[Stable Fix]
These fixes are the only changes between config-package-dev 4.12 and 4.13, so this qualifies as an upstream microrelease. (Upstream Git repository: http://andersk.mit.edu/gitweb/config-package-dev.git )

[Test Case]
Build any package that uses config-package-dev diversions, such as debathena-quota-config:
http://debathena.mit.edu/apt/pool/debathena-config/d/debathena-quota-config/debathena-quota-config_1.4.dsc
and note that the resulting binary has ‘Conflicts: diverts-’ instead of ‘Conflicts: diverts-usr++bin++quota’ (hence any two such packages will conflict with each other).

[Regression Potential]
Because this has been well tested already, regressions are unlikely. config-package-dev is a development package and not user-facing, and it currently has no reverse-build-dependencies in the archive, so any regressions will be low-severity.
