invoker doesn't properly handle paths with spaces

In the case of a specified pom with a space in the path, the name isn't properly escaped. It is likely that other command line options have similar problems.
if ( !"pom.xml".equals( pom.getName() ) )

{ logger .debug( "Specified POM file is not named \'pom.xml\'. Using the \'-f\' command-line option to accommodate non-standard filename..." ); // FIXME: Handle quotes in localRepo directory path... cli.createArgument().setLine( "-f " + pom.getName() ); }
