Find definition of environments

Issue #5 new
Former user created an issue

This is a feature request.

Now that definitions of commands/macros can be found using texdef, I think it will be cool if I can also find environment definitions.

LaTeX 2e defines environments as macros internally, e.g. \begin{center} is defined using \center and \end{center} as \endcenter.
Simply use texdef -t latex center endcenter to show the complete environment definition.
Another example texdef -t latex -s quote shows the original environment code of the quote environment.
