I could add something about how this is "temporary" although I have no
idea about the timeframe. ;-)

Agreed and I believe that's the long-term goal. I could replace this
preparatory patch with another one where I move api-builtin.txt into
builtin.h or git.c (and document SUPPORT_SUPER_PREFIX if that's
wanted). That's probably better, since right now, patch 2/7 adds
basically the same documentation for the new flag in two places.
