Indentation:

myfunction(A, B, C,
     D, E) ->

Alignment:

myfunction(A, B, C,
            D, E) ->

But also, skipping the indentation that would be to the left of these 
assignments...

No alignment:

A = 1,
Bartender = 17,
Car = 35,

Alignment:

A         = 1,
Bartender = 17,
Car       = 35,

Hopefully it'll show up properly in the email.
