wagon-scm (svn provider) - large paths under windows breaks download.

I have a deep path in windows, plus a repository housed in svn.

When performing a 'mvn compile', it fails with not finding the artifact.

Using mvn --debug shows no error message from wagon-scm (svn).

If I go into the target/checkout/.... directory, i see an empty directory with the '.svn' working directory.
performing a 'svn update .' in that directory reveals the reason ...

$ svn update .
svn: Can't open file '.svn/text-base/maven-repository-indexer-1.0-20060418.201022-1.jar.md5.svn-base': File name too long

I think a general "if windows, and path exceeds maximum, throw error before attempting process' kind of functionality needs to exist.
