Document how to use -> to highlight the current selection

[Wilfred]

The docs at http://oremacs.com/swiper/#introduction say:

For example, adding a custom display function that points to a selected candidate with ->, instead of highlighting

However, I can't find any documentation for how to do this. I've found ivy-set-display-transformer, should I be using this? Is there sample code somewhere? The -> from ido-vertical is one of the very few things I miss when using ivy.

Use:

(setq ivy-format-function 'ivy-format-function-arrow)

Thanks. Should I submit a PR for the docs, or does this belong elsewhere?

Editing the docs is better, especially since you have a CA. But putting more info on the wiki is always welcome as well.

I do indeed! :) Is that public information somewhere, or have I said so at some point?
