You're right, on Windows there's an assumption that package foo is in 
directory foo.  But I don't see why this is a big problem.  Can't you 
just check out pkg into foo, e.g.

svn co svn://svn.r-forge.r-project.org/svnroot/foo/pkg foo

(Not that I'd be against accepting a patch to remove this restriction; 
occasionally it might be nice to have two versions of the same package 
side-by-side.)
