Unable to checkout source if scmurl has spaces at the end

When scmurl has white space at the end, continuum fails to checkout source

here is an example of cvs

Provider message: The cvs command failed.
Command output:
-------------------------------------------------------------------------------
cvs server: cannot find module `oi ' - ignored
cvs [checkout aborted]: cannot expand modules
-------------------------------------------------------------------------------

When scmurl has leading white spaces, contiuum rejects it. Can we just do a trim()?
