This patch cleans up a handful of small issues left over from the sprawling
bug #63354.  Details are in [https://savannah.gnu.org/bugs/?63354#comment55
comment #55] there.

This patch does not reflect Branden's follow-up comment about U+0082.  The
patch alters only code comments, and merely advises on a future change to
handle U+0082, which is gated on bug #58958.  Branden proposes also gating on
bug #40720, but my follow-up to him explains why I believe this is
unnecessary.  However, if he feels it's important, one of us can alter the
patch to mention #40720 also.

Changes this patch makes:

    * Explain meaning of U+200B, whose name (ZERO WIDTH SPACE) does not make
      its purpose obvious.
    * Change commented-out definition of \[u200B] to one that will work once
      the offending bug is fixed.
    * Document why \[u0082] should be treated the same as \[u200B].
    * Correct a bug number.
    * Document a possible future refinement of \[u2052].
