This is the way I would do it:

\include "english.ly"
global = {
\repeat volta 2 {

\alternative

{ s1 }
}
}
melody = \relative c' {
c4 d e f |
{ r2 r4 g4 }
{ c,1 }
}
words = \lyricmode {
do re mi fa
{ so }
{ do }
}
\score {
<<
\new Staff << \global \melody >>
\addlyrics { \words }

Now, if the structure changes (e.g., you make the volta
alternatives ten bars each, instead of one) you only have to
change it in one place (i.e., the global variable).
[n.b. The {} inside the melody and words variables are, in this
version, unnecessary -- however, I find they help my eye to
distinguish the structure of the volta.]
This is unfortunately not a good habit and I remember several
emails on the mailing lists over the years where people have got
problems because they have used this solution. Since I'm getting
senile I cannot recall exactly what the problem was (an immediate
problem that comes to my mind is that \unfoldRepeats won't work).
I don't know about several emails, I know of mine, http://
lists.gnu.org/archive/html/lilypond-user/2008-10/msg00533.html where
I posited exactly this, and mats helped me to understand that,
although cumbersome, putting the repeats into every voice was the way
to go.
Also, what you do breaks the basic idea that the input to LilyPond
should describe the musical content, since the repeats are in
integral part of the music. Clearly, the musical meaning of
\repeat volta 2 {c4 d e f } g1
differs from
c4 d e f g1
You seem to view the repeat signs just as notational
embellishments, which I don't agree with.
On the other hand, for the lyrics, it probably solves the original
typesetting problems to just remove the \repeat and \alternative
from the lyrics. Still I don't find that a completely satisfactory
solution. It seems that what happens is that the repeat related
commands are attached to the following syllable. Unfortunately, it
wouldn't solve the problem to instead attach them to the preceding
syllable since that would break if there's a rest before the repeat
sign.
