Set correct path for flake8.

flake8 check did not work correctly for rpmlb directory. flake8 did not complain for not existing directory lib/rpmlb/.

Actually current source has below result for flake8.

$ flake8 rpmlb/ tests/ setup.py
rpmlb/cli.py:37:80: E501 line too long (84 > 79 characters)
rpmlb/cli.py:78:80: E501 line too long (95 > 79 characters)

I added "--show-source --statistics" because those look more useful options.

$ flake8 --show-source --statistics rpmlb/ tests/ setup.py
rpmlb/cli.py:37:80: E501 line too long (84 > 79 characters)
    type=click.Path(exists=True, file_okay=False, writable=True, resolve_path=True),
                                                                               ^
rpmlb/cli.py:78:80: E501 line too long (95 > 79 characters)
    """Download and build RPMs listed in RECIPE_FILE under RECIPE_NAME (such as 'python33')."""
                                                                               ^

Personally, I would split the commit into two (i.e. "Set correct path for flake 8" and "Fix style issues" or similar), to have one conceptual change in one commit.

That would be better, yes. Still, better as is than nothing.

OK, I will split those to 2 commits. I am fine. In my experience in contributing open source project, move than 100 times PR for contribution latest 1 year, I have experienced to be asked to split commits by other people only at once, as far as I know. I guess that your sense is not majority. But I am fine.

Merged with 2 commits.
