I guess I didn't explain it very well. The checked out project had a 
directory with a leading space in it:

0 $ ls -alp
total 0
drwxr-xr-x+  3 rdawes Domain Users 0 Jun  4 14:20  webgoat/
drwxr-xr-x+  4 rdawes Domain Users 0 Jun  4 14:20 ./
drwx------+ 28 rdawes ????????     0 Jun  5 09:43 ../
drwxr-xr-x+ 10 rdawes Domain Users 0 Jun  4 14:20 .git/

Note the leading space before webgoat/?

i.e. the initial path component actually does have a space in it.

Not so, see below.

Sure. But then you cd into webgoat-local/, do an "ls -l", and you'll see 
exactly the same thing I showed above.

I'm still running your command above, but I'm seeing

W: -empty_dir: trunk/ webgoat/main/project/JavaSource/org

Note the space       ^

Um, I think that you did exactly what I said I did, namely removing the 
"trunk" component from the URL. Contrast:

Yours:
$ git-svn clone -T trunk http://webgoat.googlecode.com/svn/ \
     webgoat-local

Mine (original):
$ git-svn clone -T "trunk/ webgoat" \
     https://webgoat.googlecode.com/svn/trunk/
                                        ^^^^^
Mine (eventual):

$ git-svn clone -T "trunk/ webgoat" https://webgoat.googlecode.com/svn/

I'm sure there WAS a misunderstanding. It was me not understanding how 
to translate an SVN command line to a proper git command line, 
accounting for trunks, etc. That was one of the reasons I made the post, 
to clear it up, and to make sure that anyone searching for hints on how 
to use git to clone google code projects will find something, since I 
didn't.

So, it seems that the rule for googlecode is something like:

If the published command line is:

  svn checkout https://<project>.googlecode.com/svn/trunk/ <project>

You can clone this project using git-svn with the following command:

  git-svn clone -T trunk https://<project>.googlecode.com/svn/ <localdir>

If this results in too many levels of directories in the checked out 
project (e.g. "/workspace/webgoat/ webgoat/"), take the extra directory 
component and add it to the -T parameter (e.g. "-T 'trunk/ webgoat'")

Hopefully this helps the next person.

Thanks for your response.
