Upstream: google/google-java-format#1467 | Kind: idea | Priority: low

Open PR google-java-format#1467 (fixes issue google-java-format#1258): visitReturn always emits a space before the
expression, so return """ stays on one line. Google Java Style 4.8.9 wants the opening
delimiter of a text block on its own line; the PR detects a text-block literal and emits
a forced +4 break before it, like assignments and variable initializers.

Why it matters to us: our visitReturn is identical (no text-block case), so GOOGLE style
output disagrees with the style guide. For PALANTIR style we keep text blocks attached in
method chains (the isTextBlock special case in visitDot), so the change may be wanted for
GOOGLE style only.

Affected files in our repo:

• open-java-format/src/main/java/com/palantir/javaformat/java/JavaInputAstVisitor.java (visitReturn, around line 1807)

Suggested action: investigate. Check how both our styles currently format return """
and how assignments with text blocks are laid out; adopt the idea for GOOGLE style if the
result is consistent with our assignment handling.

Filed from an upstream-watch ticket after manual review.
