bug#20227: 11.88.3; indentation of \[ ... \] environment is broken

[Todor Tsankov]

------------------------------------------------------------------------

The automatic indentation of the \[ ... \] environment does not seem to
work correctly. Of the three examples below only the first one looks
right.

I obtained those results by selecting the entire environment and running
indent-region.

Thanks for looking into this.

\[
  x
\]

\[
  \begin{split}
  x &= y \\
  y &= z
\end{split}
\]

\begin{itemize}
\item Some text here
  \[
  x
\]
\end{itemize}
