[scudo] Make comment compatible with gcc

[Caslyn]

gcc interprets a backslash '\' as the last char before a new line as a line continuation character, even in a comment context. This can produce an "error: multi-line comment [-Werror=comment]".

This PR places an innocuous '.' following the '' so that the comment can compile with gcc.
