Using the snippet you provided and running against 2.19.81, I do not see
the barline you are seeing. (See attachment: upbeat-repeat.preview.png)
It would seem that the newer version handles implicit partial measures
automatically.
One option is to use \partial explicitly, however LilyPond 2.18.2 warns
about this practice. 2.19.81 does not:
%%%%
\repeat volta 2 { d8 d | d4 d d | }
\alternative {
{ \partial 2 d4 d }
{ e4 e4 e4 | }
}
%%%%
You could also simply change time signatures secretly:
%%%%
\repeat volta 2 { d8 d | d4 d d | }
\alternative {
{ \omit Score.TimeSignature \time 2/4 d4 d }
{ \time 3/4 e4 e4 e4 | }
}
\undo \omit Score.TimeSignature
%%%%
That option seems to work in both 2.18.2 and 2.19.81 without any
warnings.
