PR checklist

• Addresses an existing issue: #0000
• New feature, bugfix, or enhancement
  • Includes tests
• Documentation update

Overview of change:

Rule that requires or restricts whitespace after branching keywords (for, if, switch, ...). Can be used instead of check-branch option of whitespace rule.

Motivation: check-branch only checks the presence of space but is invalid for the inverse situation, when a space after branch is forbidden

@arhontmw why introduce this as a new rule instead of improving the existing whitespace rule? i would greatly prefer one solution for each problem.

The "nil" is weird

Sorry, this is stale and we are de-prioritizing formatting rules as per #4534. This functionality won't get added as a new rule, but if there is a lot of demand, we might want to add the check to an existing rule.
