Thanks, it works now but now I'm wondering if the change will pollute
the obarray? Also can `intern' fail at any point because imenu is also
used by text-modes like org-mode whose heading can have any ol'
character---a quick test in an org file seems to have no problem
however, but I'm interested to know regardless.
