Consistent page layout

[Fibonacci Prower]

Hello.

I've created a score using Lilypond 2.12.2 (source code is at the
end). Unfortunately there are two things which I haven't been able to
fix:
1- The text "Da capo al Fine", which appears right at the end - or at
least should, is displayed as "Da capo al Fin". This, of course, is
because the whole line does not fit in the page. How can I move it to
the left so that it fits?
2- On the first page, the first system appears right on top and the
second one on the bottom. On the second page, the second system
appears on the middle of the page, and the bottom part looks empty.
How can I make the pages look consistent?

Thanks in advance.

The aforementioned code:

\version "2.12.2"

#(set-default-paper-size "letter")

\header {
  title =       "Himno de los Andes"
  subtitle =    \markup { \small "Voces mixtas" }
  composer =     "Luis Antonio Escobar"
  tagline = { }
}

global = {
  \time 4/4
  \key c \minor
  \override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
  \override Score.RehearsalMark #'direction = #down
  \skip1*12 \mark "Fine" \break
  \skip1*14 \mark \markup {\small "Da capo al Fine"}
}
