#3433: Omitted # after LANGUAGE pragma causes panic

------------------------+---------------------------------------------------
If the # in the closing #-} after a LANGUAGE pragma is omitted, GHC
panics. For example, creating a file containing the single line:
{{{
{-# LANGUAGE TypeFamilies -}
}}}
and passing it to GHC or GHCi produces:
{{{
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.3 for i386-unknown-linux):
getOptions'.parseLanguage(1) went past eof token
}}}
