From: Michael Haggerty <mhag...@alum.mit.edu>
Remove any references that were received from the remote from the list
(*nr_heads, heads) of requested references by squeezing them out of
the list (rather than overwriting their names with NUL characters, as
before). On exit, *nr_heads is the number of requested references
that were not received.
Document this aspect of fetch_pack() in a comment in the header file.
(More documentation is obviously still needed.)
