Tidy: Indentation of dash forms

See, e.g. <https://github.com/magnars/dash.el/pull/375>.

Ultimately I'd prefer to indent with one distinguished argument, but
the noise it causes downstream is likely not worth it.  (And,
unfortunately, the indentation of the built-in thread-first and
thread-last forms has changed to be like this as well, which is even
worse, causing 10-11 characters of extra indentation in those forms'
bodies!)
