Smart-scan does not ignore comments

[ThibautVerron]

Hello,

Judging from these lines in the package, smart-scan should jump over occurrences of the symbol/word in strings or comments. It works for strings, but not for comments.

Steps to reproduce:

1. Enter the *scratch* buffer

2. Enter the following

   test
   ;; test
   "test"
   ;; test
   test
   

3. Place point on the first test

4. Press M-n

As I understand it, point should jump to the last test, instead it jumps to the second and fourth before fifth.

Thanks!
