Repeats. Again.

[Walter Hofmeister]

Hello all,
    I am still having trouble with getting repeats with alternate endings
and the key signature spacing to work out. The code for the file in question
follows. The problem is that the key signature is being placed after the
repeat for the B section. As I am new to Lilypond, it has taken me a week to
figure out the procedure for tweaking objects and I frequently find that I
am still confused. I am not a programmer and figuring out the correct syntax
from the Internals documentation does not seem intuitive to me. I guess I
could use more examples in the documentation as many of the variable that I
investigated had a default value that is unset so this can make it difficult
for me to figure out how to set a value.
    Anyway here is the file:

\include "paper23.ly"

\header {
    title        = "Battle of Aughrim"
    subtitle    = " "
    instrument    = " "
    meter        = " "
    source        = " "
    composer    = "Trad. Irish"
    copyright     = " "
    tagline        = " "
    }


melodyNotes = 
    \notes {
    \key g \major
    \relative c' {
    %A section
    
    \repeat volta 2 {
    b8 a g fis e fis g a
    b a g fis e2
    a8 g fis a d4 a
    b4 a b8 cis d4
    b8 a g fis e fis g a
    b a g fis e2
    a8 g fis a d4 a
    fis4 e e2 }
    
    %B section
    
    \repeat volta 2 {
    fis'4 e e d8 cis
    b4 a d4. a8
    b4 a d a
    b4 a b8 cis d e
    fis4 e e d8 cis
    b4 a d4. b8
    a8 g fis a d4 a }
    \alternative {
    { fis4 e e2 }
    { fis4 e e2 }
    }
    \bar "|." 
    }
    }
    

    
\score {
    \notes {
    \clef "treble_8"
    \time 4/4
    \melodyNotes
    }
    
    \paper { }
    }

If someone could try this file and make a suggestion as to how might be the
best way to tweak it I would be most grateful. Thanks in advance.
