As Clément wrote, you could use `\\='more' if you want the curled 
version to look like ‘'more’. However, the curled version shouldn't look 
like that. It should look like ‘more’ without the apostrophe. Doc 
strings should talk about the values in question, not about code that 
would yield those values.
