Proper Handling of spaces in attributes

[WolfgangFahl]

In linux shell environments an argument list of
a b c d
is 4 arguments
'a' 'b c' 'd'
is 3 arguments

https://stackoverflow.com/questions/29964638/args4j-list-arguments-that-contain-space-not-handled sounds as if the arguments are not handled this way but my test shows that
that using @argument the arguments in the resulting list are handled in a linux shell compatible way.
Is this version dependent or the same behavior for all versions?
