Previously it wasn't consistent; some `@`s had spaces and some didn't - I made the choice to use the space because I thought it seemed like a more natural grouping as the `@` is suppressing the output of the entire command which itself may contain spaces, so the no-space style to me seems to overly tie the `@` to the first argument of the command somehow.

Anyway...just a very trivial style preference for me (mostly wanted to make it consistent), if this is highly unconventional/confusing I don't mind switching to the no space style.
