Merge branch 'jc/maint-diff-patch-header' into maint
"git diff-index" and its friends at the plumbing level showed the "diff --git" header and nothing else for a path whose cached stat info is dirty without actual difference when asked to produce a patch. This was a longstanding bug that we could have fixed long time ago. By Junio C Hamano * jc/maint-diff-patch-header: diff -p: squelch "diff --git" header for stat-dirty paths t4011: illustrate "diff-index -p" on stat-dirty paths t4011: modernise style
