Even though it seems like the autopunctuation key accepts a list of 
values this isn't the case
at the moment. Only values from the following list are valid arguments 
for the key:

- yes
- no
- all
- comma
- yes,semicolon
- comma,semicolon
- all,semicolon

The reason for this is that values like "all,semicolon" are treated as 
keyword and the comma
is part of the keyword, this means you can't change the order of the 
words and even spaces
after the comma make the argument invalid.
