'--' is translated into '–' on html documentation

[xdelaruelle]

Quite confusing as –argument and --argument are not the same thing and only the latter is expected by the module command.

This issue can be seen for instance on RTD for the description of the append-path moulefile command: https://modules.readthedocs.io/en/stable/modulefile.html#modules-specific-tcl-commands.
