spaces lost in tags with shapepar

[mbertucci47]

With the shapepar package, spaces are lost in the tags. I can't tell if this is a real issue or just an issue with Acrobat's display. Also, for some reason uploading the resulting pdf to ngpdf errors.

looks like it is losing the spaces at the end of line probably because it is building individual line boxes. In addition it build a bunch of empty paragraphs, most likely because paragraph tagging is activated while it is building trial results. Bottom line I think it is best called incompatible even though it might be simple to fix.
