[PATCH 03/10] add: free leaked pathspec after add_files_to_cache()

After run_diff_files, we throw away the rev_info struct, including the pathspec that we copied into it, leaking the memory. this is probably not a big deal in practice. We usually only run this once per process, and the leak is proportional to the pathspec list we're already holding in memory.

But it's still a leak, and it pollutes leak-checker output, making it harder to find important leaks.
