Usually it is not desirable to have content to be typeset verbatim
highlighted according to LaTeX syntax. Therefore this content will
be fontified uniformly with the face font-latex-verbatim-face.
font-latex differentiates three different types of verbatim
constructs for fontification. Macros with special characters like | as
delimiters, macros with braces, and environments. Which macros and
environments are recognized is controlled by the variables
LaTeX-verbatim-macros-with-delims,
LaTeX-verbatim-macros-with-braces, and
LaTeX-verbatim-environments respectively.
