Wrap long lines to fit within 80 columns across the codebase

Pure whitespace/line-break reformatting (braces, newlines, and line
continuations matching this codebase's existing wrap conventions) - no
logic, string content, or identifiers changed anywhere. Confirmed via
diff against the pre-change tree and by rebuilding + re-running the
affected test suites, which produce identical pass/fail results.
