Fix Formatting Rules for CASE ... END Clause

[xterao]

Updated the formatter to correctly set line-break flags for "WHEN", "ELSE", and "END" within a "CASE" expression.

---

Formatting Behavior

• The first "WHEN" clause remains inline with "CASE".

• The second and subsequent branches ("WHEN", "ELSE") are:

  • Line-broken
  • Indented to align with the first "WHEN".

• The "END" keyword is right-aligned with the initial "CASE" keyword.

Example (Formatted Output)

SELECT CASE WHEN div = 'A' THEN 'AAA'
            WHEN div = 'B' THEN 'BBB'
            ELSE 'CCC'
        END AS divName
  FROM users
