I've found a bug in the OSM API v0.6 - is there a bug tracking system I
can log it to?
Details:
<<<<<<
The bug is this: when downloading a large amount of data by specifying a
rectangular bounding box, quite often the south east corner is missing.
Some evidence: note the sizes of downloaded data in the following requests:
$ curl
http://osmxapi.hypercube.telascience.org/api/0.6/map?bbox=-88.546,41.327,-86.97,42.382

$ curl

The second request is for a smaller area - an area entirely included in
the bounds of the first area, and smaller on every side - yet more data
arrives (311M instead of 308M) showing that something is awry.
