Documentation/SubmittingPatches::[real-name], a part of the DCO section of the document. > builtin/merge-tree.c | 24 ++++++++++++++++++++++++ > 1 file changed, 24 insertions(+) A new feature should be protected by new tests to make sure it will not be broken accidentally by others. Probably a couple of new tests to both t4300 and t4301? $ git shortlog -sn --no-merges --since=6.months builtin/merge-tree.c t/t430[01]*.sh tells me that Elijah and Ævar had been active, but by looking at the output of $ git log --author=Ævar --since=6.months builtin/merge-tree.c t/t430[01]*.sh shows that the contribution by the latter was solely about code clean-up with Coccinelle and not about code features and correctness, so for a new-feature change like this, I'd ask comments by Elijah if I were writing this patch.
