~/.gitconfig: Enable "new" git push default behaviour.
~/.mailcap: Better pandoc opts, list rars.

Should add zips and whatnot probably.
~/.vimrc: Enable persistent undo.

From tpope's [vim-sensible](https://github.com/tpope/vim-sensible).
~/.vimrc: Highlight current column.
~/.vimrc: Navigate long lines naturally.

(I.e. as if they were actual lines, as most other editors do.)
~/.vimrc: Don't load rcodetools if they don't exist.
~/.vimrc: Load rust syntax support.
~/.vimrc: Use vundle.

It updates dependencies, which is nice, and documents which plugins I
use at the same time.
~/.zshrc: Use dashes as seperators in completions.
~/.zshrc: Moar history.
~/.zshrc: Emacs keybindings (i.e. readline default).
~/.zshrc: Make ls prettier.

TODO: Use ~/.aliases file.
