7title: Test fixture exercising parser corner cases
8
9description: |
10  Covers patterns that previously broke the classifier:
11    - "/* ... */ code;" with code following the closing of a one-line
12      block comment must still parse the code.
13    - a label on a node whose name starts with a digit (1wire@10).
14    - a multi-line C preprocessor macro using backslash continuations
15      must not be parsed as DTS lines.
16    - a /* comment that opens and closes on the same code line must
17      not leave the parser in block-comment state.
