* apt-pkg/contrib/fileutl.cc:
- Fix the newly introduced method GetListOfFilesInDir to not accept every file if no extension is enforced (= restore old behaviour). (Closes: #565213) * apt-pkg/policy.cc: - accept also partfiles with "pref" file extension as valid * apt-pkg/contrib/configuration.cc: - accept also partfiles with "conf" file extension as valid * doc/apt.conf.5.xml: - reorder description and split out syntax - add partfile name convention (Closes: #558348) * doc/apt_preferences.conf.5.xml: - describe partfile name convention also here * apt-pkg/deb/dpkgpm.cc: - don't segfault if term.log file can't be opened. Thanks Sam Brightman for the patch! (Closes: #475770) * doc/*: - replace the per language addendum with a global addendum - add a explanation why translations include (maybe) english parts to the new global addendum (Closes: #561636) * apt-pkg/contrib/strutl.cc: - fix malloc asseration fail with ja_JP.eucJP locale in apt-cache search. Thanks Kusanagi Kouichi! (Closes: #548884)
