Support highlighting fill-column overflows
This was previously semi-supported. There were two problems, however: 1. My fill-column value of 80 got out-of-sync with my white-line-column value of 100. Solution: globally define wpc/fill-column, set that to 80, and consume the new const in my config. 2. Nothing was activating whitespace mode. Solution: add whitespace-mode to prog-mode-hook. This SO answer helped tremendously: https://stackoverflow.com/questions/18855510/have-emacs-highlight-characters-over-80
