I mean above that snippet, i.e. this:

    +       my @remotelist = $remote_heads ? git_get_heads_list(16,
'remotes') : ()

I think that's a bit clearer, you're not left wondering why it's 16 there and 15 here, and don't have to recall that `$#remotelist <= 15` equals `@remotelist <= 16` (unless $[ != 0). But like I said, it's a nit.
