Sometimes senders draw ASCII tables and such which we get fooled into attempting highlighting and diffstat anchoring. We now require 3 consecutive diff header lines: /^--- /, /^\Q+++\E /, and /^@@ / to enable diff highlighting (whether generated with git or not). The presence of a line matching /^diff / is not sufficient or even useful to us for highlighting diffs, since that could just be part of a line-wrapped sentence. However, we'll now check for the presence of a line matching /^diff --git / before enabling diffstat anchors. Otherwise cover letters for a patch series may fool us into creating anchors for diffstats.
