Hi Christian,

Surprisingly, I just found an ASCII quote usage in vim: 
https://vim-jp.org/vimdoc-ja/

This contrast the previous examples I found. :(

In this link, various vim commands like ":set mouse=a" are quoted with ASCII 
quotes.

However, in a website about vim, square quotes are instead used for the same 
kind commands: https://web.yokkaichi-u.ac.jp/yucc/archives/2205

I thought that square quotes should be used more often, but after seeing this 
example, I change my mind ...

Puzzled and uncertain,
Huihang
