No problem for hours.  Maybe it has been completed already?
I believe I can live with it anyway.  Though I'm not quite sure
yet, the new and the old newsrc.eld files (containing non-ASCII
nnml and nnrss groups) seem to be compatible with the new and
the old Gnus mutually.  That is, I didn't need to do something
special on the newsrc.eld file.
