Thanks!  That fixed my problem!  Strangely, \vert doesn't appear in The
Latex Companion (or at least not in its index).

Two answers:

1.  eqnarray *without* the BEGIN and END blocks works.  I believe that
this is because org-mode "knows" eqnarray, but not eqnarray*.  I am
inclined to think that this is a buglet, and we should put support for
eqnarray* into org-mode.

2.  I don't believe that the BEGIN and END blocks approach is
equivalent.  If I understand correctly, the use of these BEGIN and END
blocks says "put this in only when I am exporting to Latex."  From the
manual: "...you can add special code
that should only be present in LaTeX export with the following
constructs: [#+LaTeX and #+BEGIN_LaTeX ... #+END_LaTeX]."

Adding those delimiters changes the meaning of my document.  *Without*
those delimiters, my equation goes in an HTML or ASCII export (in some
form); with those delimiters, the equation will only be exported when
exporting to LaTeX....

Best,
Robert
