i'd love to change this. this is the reason, why i had to add a function
to inverse the imaginary part when using the fftw library.
the thing is, it would change the behaviour and people might rely on the
old behaviour.
i second you and would prefer to change the behaviour ... at least in
devel, but having two different behaviours would be even worse than
having a wrong behaviour of both branches...

this is definitely something to be discussed in the irc developer
meeting that will hopefully take place, soon ...

cheers ... tim
