automaticRemotePathCreation does not create parent directories

mvn scm-publish:publish-scm -Dscmpublish.pubScmUrl=scm:svn:.../${project.artifactId}/${project.version} fails if the directory ${project.artifactId} does not exist. This happens regardless of the automaticRemotePathCreation setting. Publishing the site of a new project therefore fails unless the SVN path is created manually.

The root cause is that maven-scm-provider-svnexe does not add the "--parents" parameter to the svn mkdir command. I don't know if this should be considered a bug of the provider, or if the provider API should be enhanced to make this configurable.
