[Editorial Errata Reported] RFC5891 (3969)

Peter, I see what you're saying, but I don't think a reference to
Unicode 5.2, Section 3.6, at least not alone, is what was meant here
in Section 4.2.3.2.  If anything, perhaps this is a more appropriate
change:

OLD
   The Unicode string MUST NOT begin with a combining mark or combining
   character (see The Unicode Standard, Section 2.11 [Unicode] for an
   exact definition).
NEW
   The Unicode string MUST NOT begin with a combining mark or combining
   character.  See The Unicode Standard, Section 2.11 [Unicode] for an
   explanation of combining characters, and Section 3.6, definition D52 (et
   seq) for an exact definition.
END

John will likely have some memory of what he intended here, so let's
see what he says.
