Imagine a 30-character line shown in a 20-character wide window. How can I soft wrap it at the 25th column?
|01234567890123456789|0123456789 | window |
After scrolling till 25th character.
01234|56789012345678901234|56789 | window |
01234|56789012345678901234| |56789 | | window |
:set columns with a large number but it messed up other elements like statusline.
A similar question instead concerns with setting column number smaller than the window width.
