Fix comment that confused Haddock
Fix comment that confused Haddock

I wish Haddock did not fall over when some random non-Haddock comment
contains *'s.  I got

  compiler/rename/RnBinds.hs:732:8: error:
    parse error on input ‘-- *are not* in scope in the SPECIALISE instance pramas; e.g.’

This patch says '-- /are not/ in scope...' to pacify Haddock.
