* UPGRADE: Don't automatically do an "apt-get update" with the backup option; the behaviour is not standard, and is not so-damn-fast.
* UPGRADE: Add command line argument for --backup to specify target directory. * Used to be "wajig --backup upgrade BKDIR". * Now it's "wajig --backup=BKDIR upgrade".
* UPGRADE: Proceed to upgrade after using -b|--backup option.
* UPGRADE: Remove the option to install listed packages. This helps reduce code complexity.
* CHANGELOG: Now only displays uninstalled entries by default. This makes the hacky NEWS command redundant, which is therefore removed. (Closes: #424668).
* CHANGELOG: Add -v|--verbose=1 option to display the whole thing. This was the default option, but suggestion offered in #424668 is more sane.
* CHANGELOG: Add -x|--pager option to allow scrolling. This also implies -v|--verbose=1 (see above).
* DIST-UPGRADE: Add -b|--backup=BKDIR option to allow backing up of packages before dist-upgrade.
* BUILD: Now uses sudo instead of fakeroot to avoid permission-related. build failures for some packages (EG, fakeroot & cdbs). (Closes: #464003).
* Fix a parsing bug where "wajig changelog libgtk2.0-0" didn't work.
* Switch to dpkg-source 3.0 (native) format
* RBUILDDEPS: New option allowing one to determine which packages build-depends on a particular package. The long form command is "reverse-build-depends", else just use "wajig rbuilddeps pkgname". (Closes: #335240).
