🚀 go-pugleaf

Here is a patch to patch which i find very useful: when backing up the
patched file, automagically make the necessary directories. This
allows e.g.:

patch -B orig/ < patchfile

without worrying about directories to be created.
I also added code for systems having the mkdir system call, so that it
isn't necessary to call mkdir via system().
