I don't know if that's the best way to do it, but I'm doing exactly the 
same thing.
Except that I'd write \once \override in such a function because more 
often than not you'll have a single event where you expect a notecolumn 
clash.

by the \stemUp you force the lower voice to the same notecolumn as the 
upper. Which is true for the whole note too, although there is no 
visible collision.
The solution is to write either \stemDown or \voiceTwo before the ef 
octave. Then you don't need \ignoreClash at all because you have removed 
the clash in the first place.
