Now, module1 and module2 are completely disconnected from the trunk
they're in. That's probably not what you want. Instead, you probably
want this:

cd <project_name>
svn up module1 module2

If you don't want the entire contents of trunk, don't do "svn up" in
the trunk. Just say "svn up module1 module2" and whatever else you do
want to update.

FYI, the "svn co -N" feature is a bit broken; not sure if it'll be
fixed anytime soon. This is the bug:
