Errors in Scala syntax summary

Documentation
1

Please, which version of the Scala syntax documentation should I correct?
Specifically:

  1. Some terminals are incorrectly quoted
  2. Typo in nonterminals: HKTypeParamClause and WildCardSelector
  3. Missing production rule for SimpleType1 (typo?)

There are two syntax.md in reference and internals. Ideally they should both be fixed. reference/syntax.md tracks the official languagae standard. internals/syntax.md tracks what’s implemented in the compiler, including deprecated and experimental features. It also gives some indication what tree nodes are constructed for each feature.

Thanks for looking into this!
