What the code was meant to do, written into the code itself as a docstring

Machinery to track nesting levels of tokens. The main indicators of nesting are braces: '{' and '}'. However, the code is complicated due to braceless structures, which are control-flow structures in C-like languages. Moreover, using braces as nesting level indicators leads to a big caveat; C++ initializer lists, uniform initialization, and any other constructs with braces add extra nesting level. Another complication comes from nested classes inside function bodies and control-flow declarations/bodies. The handling of these complex cases is unspecified and can be ignored.

The check that tells the two apart

fail→pass·test/test_languages/testCAndCPP.py::Test_c_cpp_lizard::test_struct_in_param

Check file test/test_languages/testCAndCPP.py, taken without changes from the fix and copied onto the older code, so the exact same check runs against both versions.
