Description:   Opened: 2010-03-11 09:15
Sayeth the SVG specification at http://www.w3.org/TR/SVG/paths.html :

"The command letter can be eliminated on subsequent commands if the same
command is used multiple times in a row (e.g., you can drop the second "L"
in "M 100 200 L 200 100 L -100 -200" and use "M 100 200 L 200 100 -100
-200" instead)."

...and...

"If a moveto is followed by multiple pairs of coordinates, the subsequent
pairs are treated as implicit lineto commands."

This is not supported by SVN HEAD Processing, which fails to parse SVG
documents which use this feature (including InkScape with default settings).

A patch is included.
