You're right, thank you. How was such an error not spotted until now? :)

comment Passing arguments to su-provided shell
That's strange. I get exactly the results you expect (and I also agree with those expectations). I mean, in case of a second invocation, I do get "1 2 3" as an output. I'm using bash 4.2.45 on both source and destination accounts.

comment Understanding backtick (`)
@Anita: In general quotation marks does some special things (it changes the way special characters are treated - especially white spaces) but in this case, they can be dropped without much problems. This is because no special characters are used and echo command don't care about the number of arguments it gets so if b has some spaces inside, it will get multiple arguments and will still print them. This may no be the case for other commands (especially when variable is not set) so I tend to always surround variables with quotes.
