Pandoc Does Not Recognize Image Size of Inkscape SVGs

[schrieveslaach]

The development version of pandoc does not recognize SVG images create by Inkscape. Inkscape puts the xml declaration and some comments in front of the <svg> tag, for example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Pandoc complain with a warning message (could not determine image type):

[warning] Could not determine image size for 'Zeichnung.svg': could not determine image type

Pandoc does not complain when the image does not contains the xml declaration and comments:

I suspect #3462 may have fixed this.

[jgm]

Oh, sorry, I missed that you were using the dev version.
@mb21 do you want to take a look [edit: never mind, see below]?

[jgm]

Oh, I also missed that you'd submitted a PR already, sorry!
