Highlight the current column
Provides a local minor mode (toggled by M-x hl-column-mode) and a global minor mode (toggled by M-x global-hl-column-mode) to highlight, on a suitable terminal, the line on which point is. You probably don't really want to use the global mode; if the cursor is difficult to spot, try changing its color, relying on `blink-cursor-mode' or both. An overlay is used. In the non-sticky cases, this overlay is active only on the selected window. A hook is added to `post-command-hook' to activate the overlay and move it to the line about point.
