After \newenvironment that includes \end{alltt} I observe color
bleeding. In the following MWE most of the text after \end{alltt} is
fontified in font-latex-verbatim-face.

% ---------------------
\documentclass{article}
\usepackage{alltt}

\newenvironment{Code}
  {\begin{alltt}}
  {\end{alltt}}

\begin{document}
\begin{Code}

\end{document}

This issue was discussed not long time ago, see the thread here[1].
This is not strictly a bug, the \begin/\end{...} for verbatim
environments should stand in their own lines beginning with space(s)
and/or tab(s).  Rearranging the code like this works fine:

\newenvironment{Code}{%
  \begin{alltt}%
  }{%
  \end{alltt}%
}

Best, Arash

Thanks, Arash, for repeated explanation, and for the totally practicable
workaround. I think now I understand the issue with fontification in
verbatim environments.

You're welcome.  I close this issue.
