Magma Lexer Comment and Whitespace Handling
In the Pygments Magma lexer, comments and whitespace are parsed under the 'whitespace-comments' state. Standard whitespace is matched by r'\s+', single-line comments are identified with r'//.*', and multi-line comments transition to a 'comment-multiline' state via r'/\*'. Inside the multi-line state, closing tokens r'\*+/' pop the state, non-closing stars r'\*+(?!/)' are matched as comments, and all other characters r'[^*]+' continue the comment.
