I assume the word you mean by 'fourth' is 'quarter (note)' in American
English, isn't it?

Well, I agree with you the first quarter a is extraneous, it should be
dropped:

\new Staff {
       \partial 4
       \repeat volta 4 { e | c2 d2 | e2 f2 | }
       \alternative { { g4 g g } { \set Timing.measurePosition = 
#(ly:make-moment 0 4) a a a a | b2. } }
     }


but there is also a cleaner solution:

\new Staff {
       \partial 4 e4
       \repeat volta 4 { c2 d2 | e2 f2 | }
       \alternative { { g4 g g e } { a a a a | b2. } }
     }

IIRC I have already seen the second solution in printed scores, but not
the first.  Which one should we put in the manual?
