include-markdown url rewrite does not work properly with URLs which includes spaces

[davidpochobradsky]

What I want to achieve

1. I have an markdown file included.md which contains image inserted in form ![my image](<media/my image.png>).
2. I include file included.md to file master.md using {% include-markdown "../lib/included.md" start="\n---" rewrite-relative-urls=true %} (option rewrite-relative-urls is not necessary)

What I expect

I expect that URL will be rewrited and image displayed in the final document.

What I receive

The url is not rewrited and image is not displayed
