I would guess before that it didn't support labels at all unless they were
numbers; just ignored them.

Yes that's exactly the impression I got of how to do it from glancing over
a few source files.

(It creates the dig_cats)

I have several dxf files that I could test it with so yes let me know and
if we don't fully integrate v.in.dxf3d into v.in.dxf at least I could
probably merge your fix into it so it writes to dig_cats.
