(strings snipped to fit in email; one reason I don't like indents that
depend on name length :)

This is indented relative to the left paren '(Severity'.

This is indented relative to the "expression_start" at "DLA", which is
the desired behavior.


The problem is that the name "Flight_Identifier..." is contained by "=>"
; it should be contained by the expression_start. The grammar says it
is, and the expression is contained by "=>", so I don't see why this
doesn't work; I'll have to dig into wisi-containing-action.
