It might be worth pointing out that it has always been possible to let 
existing voices continue into a polyphonic section by working without 
the double backslash \\.

So, you can always write

\fixed c' {
  <g e> << { \voiceOne f8) b~ } \new Voice { \voiceTwo d4 } >> <g, b>4 
<c c'>
}

at the price of having to state \voiceOne etc. manually.

Of course you know this, but it's my impression that beginners often are 
not aware that it's possible to use << >> (inside a staff) without \\, 
so I thought I'd mention it.

(Of course, the tricky part begins as soon as _both_ voices of a << >> 
construct are to be "connected" via ties/slurs to the surrounding 
homophonic music, but that doesn't change with \voices either.)
