Indention/Line Break optimization not working

[rstemmer]

I have a svg file with empty groups and line indention (using spaces).
Applying --indent=none and --no-line-breaks does not work.

Input:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

        <g id="StatusActive_3">

</svg>

Output:

        </g>

</svg>

Note that the leading space of the stripped groups remain as well.

scour-call:

scour -i "Input.svg" -o "Output.svg" --enable-id-stripping --enable-comment-stripping --shorten-ids --indent=none --no-line-breaks

You can find a lot of small svg files that come with this issue here in my repository. Feel free to use them for testing.

I use scour 0.38.2 with Python 3.10.4
