This function may use a comment to explain what its meaning actually is.
Like, `bitmap_writer_selected_nr()` is obviously not the same as the
`selected_nr` of the `bitmap_writer`, which is quite confusing. So why
do we subtract values and why are there two different `selected_nr`s?

This flag is already used by "builtin/pack-objects.c", which may be fine.
But in any case, shouldn't we update "object.h" with both of these flags?
