Issue Summary

If a space is included after \begin or \end and the following brace, the environment is not rendered.

Ex. \begin{equation} works, but \begin {equation} does not.

(I didn't see this addressed in the docs or in previous Github issues.)

Supporting information:

No spaces:

\begin{equation}

\end{equation}

Space after begin:

\begin {equation}

Space after end:

You are correct, the search pattern for the \begin command doesn't include spaces. I will look into fixing that.
