Wasteful to run one for-each-ref for each list.

You earlier introduced $ref_item{'class'} so that you can differenciate
what you got from git_get_heads_list(); make use of it, perhaps like:

	my @heads_list = git_get_heads_list(16, \%head_class);
        my @headlist = grep { $_->{'class'} eq 'head' } @heads_list;
        my @remotelist = grep { $_->{'class'} eq 'remote' } @heads_list;

By the way, your [2/4] used "heads" and "remotes" as class, while your
[1/4] stored 'head' and 'remote' in $ref_item{'class'}.  Notice the above
suggestion corrects this discrepancy as well.
