Hi Peter,

My main reason is laziness ;) To my defense, though, it also avoids
human error.

Yes.

You can try something along the lines of
M = inv(spm_matrix(x));
MM = spm_get_space(VF);
spm_get_space(deblank(VF), M*MM);
which should work. The fine point here is that spm_get_space does not
change the orientation of the input image IF an output parameter is
defined (l2) but does if none is defined (l3). So it basically is
spm_set_space in disguise :)
Cheers,
Marko
