Enum: Use fences for code blocks

Alternatively, if `check/enum` starts with `#`, a meta array `check/enum` is used.
For example:
+```
check/enum = #3
check/enum/#0 = small
check/enum/#1 = middle
check/enum/#2 = large
check/enum/#3 = huge
+```
Furthermore `check/enum/multi` may contain a separator character, that separates
multiple allowed occurrences.
For example:
+```
check/enum/multi = _
+```
Then the value `middle_small` would validate.
But `middle_small_small` would fail because every entry might only occur once.
