string change from 0.18.0 on?

[matkuki]

Pre 0.18.0: 
    
    
    var myString = "Some String"
    echo "'", myString, "'" # --> echos 'Some String'
    

Post 0.18.0: 
    
    
    var myString = "Some String"
    echo "'", myString, "'" # --> echos 'Some String ', notice the space (null 
character)
    

Is this here to stay or a regression?
