An example of using .git as project root

[dvarrazzo]

I work with a few monorepo-style projects containing several Python packages. For instance, psycopg contains:

.flake8
/psycopg/.flake8
/psycopg/setup.cfg
/psycopg_c/.flake8
/psycopg_c/setup.cfg
/psycopg_pool/.flake8
/psycopg_pool/setup.cfg

When linting a file in psycopg/, ALE takes the psycopg/ directory as the project root, because it will find it several of the files mentioned in `ale-python-root:

ale/doc/ale-python.txt

Lines 24 to 40 in 8bcbb29

	ALE Python Project Root Behavior *ale-python-root*
	For some linters, ALE will search for a Python project root by looking at the
	files in directories on or above where a file being checked is. ALE applies
	the following methods, in order:
	1. Find the first directory containing a common Python configuration file.
	2. If no configuration file can be found, use the first directory which does
	not contain a readable file named `__init__.py`.
	ALE will look for configuration files with the following filenames. >
	MANIFEST.in
	setup.cfg
	pytest.ini
	tox.ini
	.pyre_configuration.local

so it won't apply the root .flake8 project, which we need in order to run flake in CI on the entire project.

I have just noticed the ale_root setting: I assume that would do. Have you got an example about how to configure ALE in order to use the directory containing .git as project root?

Thank you very much!
