commentline in emacs-lisp mode is strange

[Lucartas]

Using the commentline snippet in a elisp file produces this result:

                                        ; comment ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

As I understand it, the commentline snippets starts with yas-trimmed-comment-start which basically is comment-start which is ; but I guess that actually the expected behaviour would be to have a double semi-colon here starting the comment without the extra indentation.

If the current behaviour is as intended then ok, otherwise I'm willing to open a PR to fix this.

Cheers!
