Trying out rust-mode in emacs, and set rust-indent-method-chains because I like me some aligned dots.

It does what it advertises, but for some reason shoves the beginning of the line (and thus the lines underneath it) over one more tab.

I'm using spaces for tabs, configured to width 4.

What I expect:

let x = thing.do_it()
             .aligned()
             .more_alignment();

What I get:

    let x = thing.do_it()
                 .aligned()
                 .more_alignment();

I am using el-get to install rust-mode so it should be pulling off the latest master.

Yes, I've observed this as well and it made me sad because the option is so beautiful when it works.

I'm having problems identifying just when this problem arises. It's not as simple as presented in the topic here. A standalone example would be helpful.

[nikomatsakis]

Ah, hmm, maybe it is. I just didn't have the option fully enabled.

I have a kind of working patch for this. It's sort of ad-hoc. I'm going to use it for a bit locally and submit it if it seems to be going ok.
