Why add to_ret when you can use the existing variable err directly? Or
at least remove it when it's not used anymore.

If you free the memory of the strbuf at the end of the function then
there is no point in keeping it static anymore. Growing it to PATH_MAX
also doesn't make as much sense as before then.
The patch makes git archive allocate and free the path strbuf once per
archive entry, while before it allocated only once per run and left
freeing to the OS. What's the performance impact of this change?
