Yeah hard to describe. Assume that both the A and B part have a quarter note pickup measure. These pickups bars differ from each other. The first alternative in the A section will end with the notes from the A anacrusis. The second alternative in the A section will end with the notes from the B anacrusis. So the A alternatives differ.
In the B section the first alternative will contain the notes from the B anacrusis. The second B alternative will be a short measure with a space for the final quarter note.
Here's my melody line markup for The irish Washerwoman (there are a couple of custom macros here, but the sense should be obvious):
melody = \relative g' {
\global %key signature
\set Score.markFormatter = #format-mark-circle-alphabet
\partial 4 d'8 c
\mark \default
\repeat volta 2 {
b8 g g d g g |
b g b d c b |
c a a d, a' a |
c a c e d c |
b g g d g g|
b g b d c b |
c b c a d c|
}
\alternative {
{b g g g d' c|}
{b g g g g' a |}
}
\dfrepeat
\break
\mark \default
\repeat volta 2 {
b g g d g g |
b g b b a g |
a fs fs d fs fs |
a fs a a g fs |
e g g d g g |
c, g' g b, g' g|
c, b c a d c |
}
\alternative {
{b g g g g' a}
{b g g g s4}
}
\ebar
\label #'lastPage
}
I'm still on 2.18 so I haven tried the multiple anacrusis capability.

What's wrong with using proper repeats?
