Comment 8 for bug 1659347

Seems to work fine on Windows 10, Inkscape 0.92.1pre0 15346 (64-bit)

There are two minor glitches (but I doubt they're caused by this change?):
1. Assume an image file "E:\test\raster.png"
2. Open a new document, embed raster.png and save to "E:\test\drawing.svg". Although the file is in the same directory the full path is saved 'xlink:href="file:///E:/test/raster.png"'. One can avoid this by saving the file once before embedding raster.png
3. Immediately after saving to "E:\test\drawing.svg" in 2. save the file again to ""E:\drawing.svg". You will now end up with 'sodipodi:absref="E:\test/raster.png"' in the saved file.

@jazzynico: You had a look at the relevant code lately. Maybe you can check it out? I guess at least 2 is worth figuring out (for future versions) while most likely not a regression. 3. is obviously only a minor thing.
