(U+51E3): Use `=>daikanwa' instead of `morohashi-daikanwa' for
M-01740.
(U-00020652): Use `->subsumptive' to integrate M-36670; use
`ideographic-{radical|strokes}@ucs' instead of
`ideographic-{radical|strokes}'; add
`ideographic-radical@ucs*sources',
`ideographic-{radical|strokes}@daikanwa=36670' and
`ideographic-radical@daikanwa=36670*sources'.
(M-01781): Unify U-00020654 and H1-DF6D.
(M-01782): Unify U-00020655 and H1-DF6E.
