### Fixed
- The dots of a chain that breaks are indented past the head of the chain, instead of landing on the head's own column or to the left of it. A dot on the head's column reads as a new item rather than as the chain continuing, and inside a parenthesis the parser refuses the output outright: `let v = ((someObject.First(a).Second(b).Third(c)))` at two-space indentation produced code Fantomas would not accept from itself, so the file was left unformatted with a bug report on the console. The dots now step one indent level at a time until they clear the head, which keeps every column a multiple of the indent size; a chain whose dots already cleared its head is untouched. This replaces a branch that anchored a parenthesised chain on its opening parenthesis, written when only a real dot chain reached it. Since `8.0.0-alpha-014` a dotted long identifier is a chain too, so it also fired for the likes of `Seq.map`, which never breaks, and moved a lambda written behind such a call three columns for no reason.
