a line starting with '<' means take out the line, a line with '>' is to
be added, the line number indicate where. So for example
247,251c242
< core Transform
< {
< matrix 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1
< attachments [ ]
< }
---
> core NULL
mean from w1.osg to the new output, the 5 lines concrete core instance
are replace by single 'core NULL' line.

not necessarily, I tried it with the one you gave
and could not recreate it so that one should be fine. I can
switch reasonably fast between revisions.

the problem is that the beacons referenced are not written into the file
other than in the beacon location itself. So on reloading this will
fail. So if you want to export these elements you have to write the
node referenced as well.
