What do you do with Cobol? 
I’ve never even tried to make stuff fit into 80 columns - one of the big advantages of today’s resolutions is that 120-160 columns is so easy! Mind you, C tends to end up fitting anyway…
As for editors - I’ve had to change so many times that it almost doesn’t matter anymore… I just avoid BOTH Vim and Emacs! The best I ever used was a little gem written in assembly on the Amiga: CygnusEd Professional. It could easily get over 3,000 search and replace ops/sec, allowing ‘shorthand’ coding - and the columnar ops were simple too, via mouse or keyboard.
How’s that for OT while on topic?
