The patch files are written to the current directory, e.g. 0001_xxx.patch

branch (str): Branch to create patches from (None = current)
count (int): Number of patches to produce, or -1 to produce patches for
the current branch back to the upstream commit
start (int): Start partch to use (0=first / top of branch)

ignore_binary (bool): Don't generate patches for binary files
Returns:
Tuple:
