Default is King – breaking console and editor habits

My Half-Year's resolution:
Every day, delete one line from either my .vimrc or .zshrc files.

Today: undofile config, out!

" Preserve undo between sessions
set undofile
set undodir=~/.vim/undodir

Defaults are everywhere, let's take advantage of that.
