 " '~/.vimrc', because Vim automatically enters nocompatible mode if that file
 " is present. But we're including it here just in case this config file is

 " This enables relative line numbering mode. With both number and

 " This is useful because you can tell, at a glance, what count is needed to

 " By default, Vim doesn't let you hide a buffer (i.e. have a buffer that isn't
 " shown in any window) that has unsaved changes. This is to prevent you from "
