Rollup merge of #32679 - tclfs:patch-1, r=steveklabnik

Remove error description of `move`

(1) `x` can be used in main() after the call to spawn(). Because the variables follow normal move semantics, though the keyword `move` is used, and i32 implements `Copy`.
(2) I remove this sentence because the previous sentence gives the referrence to `move closures`, and more description of `move` may be redundant.
