Documentation for checking out and build should warn abour long path names on Windows

I tried checking out the 2.1 maven code and build to see if a problem I was seeing with maven eclipse integration was localized to the that integration or was caused by the new maven embedder in 2.1 that they use.

I was checking out into a directory on my desktop under windows. The checkout did not complete and had a message:

svn: Can't open file 'maven-components\maven-core\src\test\resources\org\apache\
maven\extension\test-extension-repo\org\apache\maven\core\test\test-lifecycle-an
d-artifactHandler\1\.svn\tmp\text-base\test-lifecycle-and-artifactHandler-1.pom.
md5.svn-base': The system cannot find the path specified.

The problem is that while windows allows filenames up to 256 characters the maximum path length it allows is 260 characters. When you add that path to the path to the desktop directory it was too long.

I was able to check it out to the root directory without problem.

The guide to building maven should probably mention that for Windows users in the part about checking out the source.
