Hi Bruno,

That looks like there's two levels of tags.  You should be able to do
this with your version of git in $GIT_CONFIG:

	[svn-remote "svn"]
		url = http://restlet.tigris.org/svn/restlet
		fetch = trunk:refs/remotes/svn/trunk
		branches = branches/*:refs/remotes/svn/*
		tags = tags/*/*:refs/remotes/svn/tags/*/*
		; note the */* to glob at multiple levels

Yeah, that's an unfortunate thing about the flexibility of Subversion,
basically anything can be a "tag" or a directory and it's extremely
hard for git svn to support any uncommon cases for tags/branches
out-of-the box, so the manual config editing is needed.
