; Similarly, exclude certain keywords (detected by a regular expression).
; If a list has 2 elements on the first line, it is aligned to the second element.

; If the first element in a list is not a list and on a line by itself, the outer list is aligned to
; it plus 1 additional space. This cannot currently be modelled exactly by our indent queries,
; but the following is equivalent, assuming that:
; - the indent width is 2 (the default for scheme)
; - There is no space between the opening parenthesis of the list and the first element

; If the first element is among a set of predefined keywords, align the list to this element

; the second line of the list should be indented by 2 spaces more in some cases. Supporting this would
; be possible but require significantly more patterns.
