In the Installation section of README.md there's a table of installation commands for users of the NeoBundle, Vundle, Vim-plug, Pathogen, and Dein plugin managers.
The Pathogen example references the following command:
git clone git://github.com/wellle/targets.vim.git ~/.vim/bundle/targets.vim
Unfortunately, GitHub turned off the git protocol. See Improving Git protocol security on GitHub.
The example should be changed to use a supported URL scheme such as "https://" or "ssh://".
