To make everything align would require shifting everything. So most
usages which don't have that wide events wouldn't fit into 80
character columns anymore. That would be worse.

Or do a two pass output that computes lengths first. But that's
fairly complicated and would prefer to not tackle this right now.

Again it's only a few cases where it is visible at all.
