Dear Maintainer,
Consider the two SVGs encosed, and the diff between them.

The only difference between them is a single comma in an "a" command.
This comma is supposed to be optional.
In <http://www.w3.org/TR/SVG/paths.html#PathDataBNF>, the most relevant
productions are:
,----
| elliptical-arc:
| ( "A" | "a" ) wsp* elliptical-arc-argument-sequence
| elliptical-arc-argument-sequence:
| elliptical-arc-argument
| | elliptical-arc-argument comma-wsp? elliptical-arc-argument-sequence
| elliptical-arc-argument:
| nonnegative-number comma-wsp? nonnegative-number comma-wsp?
| number comma-wsp flag comma-wsp? flag comma-wsp? coordinate-pair
| flag:
| "0" | "1"
| comma-wsp:
| (wsp+ comma? wsp*) | (comma wsp*)
`----
We end up trying to parse "0,16,8" as "flag comma-wsp? flag comma-wsp?
coordinate-pair". This is supposed result in a flag of "0", another of
"1", and a coordinate-pair of "6,8". No comma is needed between the "1"
and the "6", because a flag cannot be more than one digit long anyway.
Firefox and Chrom{e,ium} do fine with this.
Unfortunately, Inkscape doesn't actually manage this; instead, it
appears to abort parsing the path at this point, presumably believing it
to be syntactically invalid. This results in the enclosed actual vs.
expected renderings.
(The original version of the test SVG had only one path, which was the
concatenation of the paths in the provided version. Inkscape only
displayed through the first path, which is consistant with the path
parse error handling given in the SVG spec; namely, draw everything
before the parse error, but stop at the error. Inkscaped didn't warn
about it like the spec suggests, though, even though an SVG editor is
probably where such warnings would be MOST useful.)
