[PATCH v2 07/17] Pass nr_heads to do_pack_ref() by reference

[mhagger@alum.mit.edu]

From: Michael Haggerty <mhagger@alum.mit.edu>

This is the first of a few baby steps towards changing filter_refs()
to compress matched refs out of the list rather than overwriting the
first character of such references with '\0'.
