pu fails to build for me (with the standard 'make DEVELOPER=1 ...'),
and it appears to come from this series:

midx.c:567:15: error: ‘write_midx_pack_lookup’ defined but not used
[-Werror=unused-function]
 static size_t write_midx_pack_lookup(struct hashfile *f,

It looks like the use of this function was removed in v2 of your
series, but the function itself was left behind?  Could you take a
look?

Thanks,
Elijah
