Run cargo fmt with Rustfmt 1.6.0

- "1.6.0" now supports formatting let-else statements which we use liberally,
  and appears to have some fixes in regards to long-indented-lines with macros
  like `wgettext_ft!`
- This commit updates the formatting so that devs with the latest stable don't
  see random format-fixes upon running `cargo fmt`
