[OSM-newbies] Updating already uploaded data

[Bob Jonkman]

Hi all:  I spent the weekend cycling all over town, collecting map 
tracks. Sunday night I tagged and uploaded it using JOSM, and saved the 
file. 

Yesterday I corrected a few small errors (node positions) and added 
some additional tags (footpaths, playgrounds), and re-saved the file.

Can I upload the same file with the updates?  Will OSM create duplicate 
nodes, or does it recognize a moved node?

Thanx,
--Bob.
