It's fairly easy to put those back in w/ xmllint --format. Thom, what do
you get for:
xmllint --format for_test_here.svg | wc -l
However, my copy of OpenOffice.org (22.214.171.124) does evil things to a
pencil squiggle drawn in Inkscape. The original plain svg has a single
path (albeit w/ 451 points). After passing through ooodraw, that is
broken into 760 path elements. A quick google tells me that svg export
is one of the areas that LibreOffice has advanced in. That probably
explains the discrepancy.
So, just saying 'svg' isn't enough: we'd likely need to specify Inkscape
as the one true svg processor.
