The vim-colors-solarized-git (https://aur.archlinux.org/packages/vim-colors-solarized-git/) package is not really out of date, but it has a version number 20131007 hardcoded in, but also has a pkgver function that changes that date when makepkg is called, but this date is from 2011 when the last commit to the git repository was made. This causes the package to appear out of date to aur helpers and other packages that check for updates of aur packages.
