Passing option --smart-quotes=yes to rst2html

Nobody has claimed this yet.

I‘m trying to pass the option `--smart-quotes=yes` to `rst2html` through restview, and I’m not sure how to do that.

I’ve tried using `restview -e "rst2html --smart-quotes=yes restructuredtext.rst"`, thinking that ``--execute`` might be the answer, but that produces error messages (see below) and the page opened in Firefox looks like raw HTML code with rst2html error boxes with the same messages that are in the terminal output.

Output 1

```

```

I’ve also tried adding extra parameters to the command just in case, but that produced different terminal errors without any webpage that could be opened:

```
restview -e "rst2html --smart-quotes=yes restructuredtext.rst /tmp/rst2html-temp.html" -w /tmp/rst2html-temp.html
```

Output 2

I’m using Restview v2.9.2 installed from AUR, and Python 3.9.2 with Manjaro Linux x86-64.

Any help is appreciated.

Start by reproducing the documented restview -e commands with Python 3.9, then inspect restview/restviewhttp.py around handle_command, handle_error, and render_exception, which appear in the traceback. Check how command output and errors are passed through, and consider the rst2html option handling shown in the issue. Done means the requested command behavior is clear and failures no longer produce the reported rendering exception.
