Enum wrapping rule

[paul-dingemans]

The Kotlin coding conventions are not very specific about formatting enumerations. Android Kotlin Style Guide is more specific and can be used as a common base for all code styles. Though the exception below does not really make sense to me:

When the constants in an enum are placed on separate lines, a blank line is not required between them except in the case where they define a body.

Additional rules should be:

• All enum entries including the braces should be on a single line enum class Answer { YES, NO, MAYBE }, or in case of a multiline declaration, each enum entry is listed on a separate line.
• In case the trailing comma's are enabled and the enumeration contains another declaration then semicolon is placed on a separate line below the enumeration entries.
• In case the enumeration contains another declaration then the semicolon after the enumeration entries is followed by a blank line followed by the other declaration(s).
