Sure. Here's a diff against master, for example:

    diff --git a/support/testing/tests/fs/test_squashfs.py b/support/testing/tests/fs/test_squashfs.py
    index b205b6a55a..9fad28f834 100644
    --- a/support/testing/tests/fs/test_squashfs.py
    +++ b/support/testing/tests/fs/test_squashfs.py
    @@ -5,12 +5,12 @@ import infra.basetest
     
     class TestSquashfs(infra.basetest.BRTest):
         config = infra.basetest.BASIC_TOOLCHAIN_CONFIG + \
    -"""

    +        """
     
         def test_run(self):
             unsquashfs_cmd = ["host/bin/unsquashfs", "-s", "images/rootfs.squashfs"]

And here is a big file which is easier to read with indented config
fragments:
