I had another look at the thread and did not see any feedback that focuses
on the actual scope of the patch series. Conversions from scripted parts
of Git to built-ins are always a bit finicky (and hard to review, I
admit).

Therefore I would like to move the status to "needs review".

I do not think that there are any major issues with it (Ævar's feedback
notwithstanding, it focuses on tangents that should be addressed after the
conversion, to avoid losing focus), but I would love to see a thorough
review of the conversion to avoid obvious regressions like the one in the
built-in interactive `add` I had to fix recently.

Ciao,
Dscho
