Description
rustfmt wants indentation like this:
foo(
// Whatnot
42,
)
.bar() // Same amount of indentation on this line as the previous line with close parenthesis.
but rust-mode does this:
foo(
// Whatnot
42,
)
.bar() // Extra indentation.

Research direction
Reproduce the two rust-mode formatting examples and compare them with rustfmt's output. Trace the rust-mode indentation logic for a line beginning with a dot after a closing parenthesis; done means the chained .bar() line aligns with the preceding closing parenthesis rather than receiving extra indentation.
