I have some problems with this code. Look:

        ragged-right = ##f
}

strangeLyricHyphens =
\override LyricHyphen #'after-line-breaking =
  #(lambda (grob)

           (bound-right (ly:spanner-bound grob RIGHT))
           (text-left (ly:grob-property bound-left 'text))
           (text-right (ly:grob-property bound-right 'text))
           (orig (ly:grob-original grob))
           (siblings (if (ly:grob? orig)
                 (ly:spanner-broken-into orig)
                 '() ))
;; Underscore-markup:
           (underscore #{

           (new-text (grob-interpret-markup bound-left #{
              \markup \concat { #text-left-mrkp #underscore }
                  #}))
           (add (* -1 (interval-length

                           (grob-interpret-markup bound-left underscore)
                              X))))
           (fake-hyphen

      (ly:grob-set-property! bound-left 'stencil new-text)
      text-left)
    (if (and (>= (length siblings) 2)
      (eq? (car (last-pair siblings)) grob))
      (ly:grob-set-property! bound-right 'stencil fake-hyphen))))

There is hyphen before first syllable at system («_lei»), but there is no
hyphen after this syllable.
Syllable «lei» in word «eleison» is no first and no final. In means what in
case of this syllable is first at system, it must have hyphen before and
after oneself.
