Fix export of parameterized LaTeX environments to HTML/SVG

Fix export of parameterized LaTeX environments to HTML/SVG

[Rudolf Adamkovič]

The Org manual states that LaTeX fragments are

  Environments of any kind. The only requirement is that the ‘\begin’
  statement appears on a new line, preceded by only whitespace.

yet, the Org document

  #+OPTIONS: tex:dvisvgm

  \begin{array}{cc|c}
    P & Q & P \iff Q \\
    \hline
    0 & 0 & 1 \\
    0 & 1 & 0 \\
    1 & 0 & 0 \\
    1 & 1 & 1 \\
  \end{array}

exports to HTML with

  cc|c

visible (and a broken array).

More generally, LaTeX environments

  \begin{ENVIRONMENT}{OPTIONS}

that include some

  {OPTIONS}

do not export to HTML well.

Well, sort of.  This particular bug is about parameterized environments,
not TikZ per se, but I get where you are coming from, looking at the bug
as a core developer, from below.

Fortunately, unlike with TikZ, a simple workaround this particular bug
exists, namely to wrap the parameterized environment within

  \begin{equation*} and \end{equation*},

so that the outermost environment, the one Org cares about, has no
parameters.  Thus, I will do that in the meantime, until the new LaTeX
subsystem is merged.
