CVS SCM URL doesn't allow passwords containing '@'

Unable to specify a password containing @, as the URL parser attempts to interpret the following text as a hostname.

scm:cvs|pserver|myUsername|MyP@ssword@host.name.bar|/foo|bar

The URL parser would extract the following hostname 'ssword@host.name.bar' which is wrong.

AbstractCvsScmProvider should offer an escape syntax.
