The flag seems to be somewhat broken on current head.   It should allow 
you to extract rgb (or xyz) channels from multiview EXRs. However, it 
only allows uppercase channels, like N.X or indirect_diffuse.R.
I'll submit a patch to fix that.

It does not work with OpenEXRs 2.0 multipart files (known limitation).
