Should we suggest to replace the parenthesis with a space in all cases, and let rustfmt cleanup after rustc?

That is an optional solution,
but it seems a little weird when the suggestion snippet is printed on console:

if let (a) = 0 {}

suggest to be:

if let  a  = 0 {}

Do you mind renaming this PR to mention the actual issue, specifically "spaces"?
