OK.  This has become much easier to read by dropping the mention of
the header file where the callee happens to be declared.

Just FYI, in my private rewrite (that I'll discard), I made it like
so:

   builtin/add.c:refresh() declares 'flags' as signed, and uses it
   to call refresh_index() that expects an unsigned value.

Good, too.

Will queue.
