Description
Description
It should be safe to remove unnecessarily nested blocks when there's no statements in between: {{{ <stmts> }}} => { <stmts> }.
Example
Input:
fn f() {
{{{{{ g() }}}}};
}
Expected output:
fn f() {
g();
}
Actual output:
fn f() {
{
{
{
{
{
g()
}
}
}
}
};
}

Research direction
No source file or test is named. Reproduce the Rust input from the issue with rustfmt, then trace the formatter entry point that handles nested blocks and compare its output with the expected flattened block; done means unnecessary empty nesting is removed without changing statements.
