Are you sure? `comment-continue` is very rarely set globally.
Usually it's set buffer-locally by `comment-normalize-vars`.

Out of symmetry, I'd have expected a SPC here.

You should also test it with that very same comment but when
`comment-start` and `comment-end` have been set to something like
"// " and "".
