I haven't played with chant in lilypond for a while, but I think I
remember that it still uses the default time signature (4/4) and note
length (crochet or quarter-note) even though these don't mean anything
in this notation.  What you are seeing is the line being broken at the
(unprinted) bar lines, which occur every 4 crochet notes.  (Note that
the podatus on 'un-' of 'unheil' is two notes.)  An even more
unfortunate side effect of this is that if you have long melimata the
spacing gets messed up, because lilypond allocates a certain amount of
space for each neume even though they are clustered together.  You can
see this in your example, where the notes above 'unheil' have too much
space between them.

I found that there was no real 'clean solution'.  I tended to have a
lot of \bar "" commands after various notes more or less around the
place where I expected line breaks to occur.  Unfortunately, I don't
think chant is very high on the list of priorities with the developers
and, to be fair, there probably isn't really a compelling reason why
it should be.  I did have a look at it once but I don't know enough
about scheme, python or chant notation to be able to get very far.
