Blank lines are not preserved in {alltt} environment

[siegfriedzoetzsche]

The {alltt} environment should preserve blank lines but alltt.tex:

    \documentclass{article}
    \usepackage{alltt}
    \begin{document}
    \begin{alltt}
    #!/usr/bin/env bash
    
    echo 'Hello'
    \end{alltt}
    \end{document}

converted with

    latexml --strict --destination alltt.xml alltt.tex

results in

    [...]
        <verbatim font="typewriter">
    #!/usr/bin/env bash
    echo ’Hello’
    </verbatim>
    [...]

Thank you for the report! There is already a test file for alltt that we should add this test into to ensure parity.

Hmm, thought that was handed, but needs to be a bit more clever. Should work now. Thanks for the report!
