Write <c g>\glissando <d f e>

Then write <e f d> as the second chord...  I would also expect ties to
try working in specified order rather than doing their own sorting.

A different approach would be if

<< { c e }
   { g f }
   { s d } >>

managed to assemble chords properly (but then putting \glissando in the
individual sequences does not keep the \glissando attached to the
respective notes: the glissando basically remembers only its point of
time within the voice, not its note of attachment).
