This is more gVim (Linux) related since Vim doesn't have a "window" of its own.
I'm trying to wrap a text at (say) 80th character, visual wrap only, no changes in file, hence no textwidth or wrapmargin.
Tried using columns=80 but this resizes the window and also counts in lines numbering (set number) which is both undesired. The former is absolutely undesired, the latter I can live with though.
Is there a way to have long lines wrapped at a certain column without having to physically format the text?
This is for readability/convenience purpose only so workarounds are welcome as well.
