I've never seen this before, but it _is_ possible.

Try this workaround:

\version "2.16.0"

\paper {
        ragged-right = ##f
}

strangeLyricHyphens =
\override LyricHyphen #'after-line-breaking =
        #(lambda (grob)
          (let* ((l-bd (ly:grob-property grob 'left-bound-info))
                 (bound-left (ly:spanner-bound grob LEFT))
                 (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)
                       '() ))
                 (new-text (grob-interpret-markup bound-left (markup
#:concat ((markup->string text-left) "_"))))
                 (add (* -1 (interval-length (ly:stencil-extent
(grob-interpret-markup bound-left (markup "_")) X))))
                 (fake-hyphen (ly:stencil-translate-axis
                    (grob-interpret-markup bound-right (markup #:concat
("_" (markup->string text-right))))
                      add X)))
          (ly:grob-set-property! grob 'transparent #t)
          (if (not (null? text-left))
            (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))))
