Subject: clang-format: [Java] Don't align after "return".
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6cab6784b927cc55eea7eef560077a963fc5a404;p=platform%2Fupstream%2Fllvm.git

clang-format: [Java] Don't align after "return".

Doesn't seem to be common practice in Java.

Before:
  return aaaaaaaaaaaaaaaaaaa
         && bbbbbbbbbbbbbbbbbbb
         && ccccccccccccccccccc;

After:
  return aaaaaaaaaaaaaaaaaaa
      && bbbbbbbbbbbbbbbbbbb
      && ccccccccccccccccccc;

Patch by Harry Terkelsen.
