Description
This is probably a consequence of the code which tries to line up . in call chains, but the following example indents oddly for me:
fn main() {
for x in foo.iter()
.map(|x| x * 2) {
let y = 22; // I expect this to be aligned with the `for`!
}
}

Research direction
Reproduce the indentation from the Rust example in rust-mode, then trace the code that aligns dots in multi-line call chains and handles the surrounding for block. Done means the iterator chain remains aligned while the loop body is indented consistently with the for statement; add or update a regression test if the existing test structure reveals one.
