quotes=preferSingle/preferDouble behave more like forceSingle/forceDouble

[jakebailey]

I have YAML like:

some_string: "This isn't working"

If I set quotes=preferSingle, the formatter outputs:

some_string: 'This isn''t working'

Even though the docs say that the opposite quote style is used to avoid extra escapes:

"preferDouble" - Use double quotes as possible. However if there're escaped characters in strings, quotes will be kept as-is. (Recommended) (Default)
"preferSingle" - Use single quotes as possible. However if there're \ char or " char in strings, quotes will be kept as-is.

Sounds reasonable. I'm going to change the behavior of preferSingle/preferDouble and add alwaysSingle/alwaysDouble options, but the default option value will still be preferDouble.

[jakebailey]

Thanks! Yes, "always" is probably the right term.

Released v0.5.0.
