Trailing slash added for indented images

[jeremynovey]

When a line has a double space at the end, followed by an indented image, a backslash appears in the build.

* Text:  
    ![image](/path/image.png)

Renders as:

* Text:\
    IMAGE

This only happens when it's an image. Adding another newline after the first line prevents the backslash from magically appearing.
