Hi Arturo, Interesting request. But... a vertical bar across the screen is hard to make -- it would mean having to extend shorter lines with whitespace to reach the desired column. What is easier to make is to color any text that exceeds a certain column.
Attached is a proof of concept. The "limit" is baked in as 68; it would of course have to become settable by some option. This doesn't give you an indication of how many columns you can still use before reaching the limit, but this is the best I can do with a simple patch. Benno
