Description
let-else always expands to multiple lines if control_brace_style = "AlwaysNextLine". I don't know if this is a bug or simply not supported.

Research direction
Start by reproducing the let-else formatting behavior with control_brace_style set to "AlwaysNextLine". Inspect rustfmt's formatting path for let-else and its existing regression tests, then determine whether the single-line form is supported. Done means the behavior is corrected or explicitly documented, with a regression test covering the result.
