Clarify `paredit-insert-comment' and change its criteria for code comments.

Formerly, this would choose code comments only when code follow the
point on the line.  Now it will insert code comments also when no
code precede the point on the line.  For example, the command will
choose a code comment rather than a margin comment in the following
fragment:

   (foo bar
        |baz
        quux)
=>
   (foo bar
        ;; |
        baz
        quux)
