The tool tip for the "Align Continuation Lines" states that the behaviour for the "Not at all" value should produce the following code:

(tab)int i = foo(a, b,
(tab)c, d)

this currently works for c++ files. The equivalent code in javascript files should read as follows:

(tab)var i = foo(a, b, 
(tab)c, d)

but the current behaviour for javascript files is the same as the default even though the "Not at all" setting is currently selected. This is the current behaviour when "Not at all" is selected:

(tab)var i = foo(a, b, 
(tab)(tab)(tab)  c, d)
