If you strbuf_detach() it...

...and call string_list_clear() you'll leak memory, since the
string_list will think that someone else is taking care of this memory.

I had some recent musings about how this API is bad, and I've got local
WIP patches to fix it, but in the meantime you need to:

    packs.strdup_strings = 1;

Before calling string_list_clear(). I.e. we didn't strdup(), but during
free() we pretend that we did, because we did, just not in
string_list_append().
