True, I forgot about that.   (It is sort of silly when the multio code
already has a `while (read()) write()' loop.)  There's always:

zsh% print -nr -- "$(<oldfile)" >newfile

or (more fun, but not necessarily less memory intensive)

zsh% zmodload zsh/mapfile
zsh% mapfile[newfile]=$mapfile[oldfile]
