This is a line-by-line conversion to append to a string property rather than print into a PHP output buffer. The changes to the base class break subclasses such as MobileFrontend's InlineDiffFormatter, which is updated in I81dd01cb. Depends-On: I81dd01cbb9ce11b87115fb1fed511027aee436a1 Change-Id: Idf2a6c593b81a152edec923d4db6272ca1f3f545
