This is my vimrc file, backed up on GitHub for safekeeping.
I named it _vimrc instead of .vimrc because I use this configuration
file under Windows too. Vim on other platforms can use _vimrc without any
problems, so this name is portable.
This vimrc uses vim-plug to pull in other plugins. It should auto-install vim-plug, but in case it doesn't, check vim-plug's README for instructions.
