Cool.  If anyone familiar with the planet dumper tool is listening...

In http://svn.openstreetmap.org/applications/utils/planet.osm/C/output_osm.c

} else if ((*in >= 0) && (*in < 32)) {
            escape_tmp[len] = '?';
            len++;

should be something like

} else if ((*in > 0) && (*in < 32)) {
            len+=sprintf(&escape_tmp[len], "&#%d;", *in);

"Something like" as in I haven't even checked if that compiles :).

Of course, another thing to consider is that 1024 bytes isn't enough for the
truly pathological cases.  I think you need like 1531 or something to handle
that.  Fixing this might be enough to properly process the current db,
though.

Any chance of adding num_changes?
