Modified laissez vibrer ties

Is there a way to extend laissez vibrer ties so that they stop just short of the barline, as in the attached
example? I can't seem to find a way that doesn't involve manually adjusting control points.

You may consider using a trick: create ties attached to hidden notes.
See http://lilypond.org/doc/v2.14/Documentation/notation/inside-the-staff#hidden-notes

RE: Modified laissez vibrer ties

I did consider that; the problem is those ties go _over_ the barline instead of stopping just short, so
they'd still need to be adjusted manually.

Not if you scale the durations:
{ r2 <b' d'' g''>2*7/8 ~ \hideNotes q2*1/8 \unHideNotes R1 }
but i admit that it doesn't look perfect.

I tried using normal ties to invisible notes after the barline and
tweaking to-barline in order to have them stop short.  I have not been
able to make to-barline have any effect, though.

Huh.

Not very elegant, but this might be a possibility:

\relative c'' {
  \override Slur #'to-barline = ##t
  a1*3/4( \once \hideNotes a4) a1
}

or, if you prefer,

\relative c'' {
  a1*3/4 -\tweak #'to-barline ##t ( \once \hideNotes a4) a1
}

Unlike hairpins, 'to-barline for Slurs seems to extend the slur to the 
_next_ bar line rather than stopping it short at the previous one.
And the hidden note seems to require a non-zero duration too.

Never mind--I found the solution: http://lsr.dsi.unimi.it/LSR/Item?id=794

I only just discovered the LSR, so I completely forgot to check there before bothering everyone here. Oops. :-P

You can change the default length of LV ties to make them longer, though
they won't adjust their length to scale to the next barline:

\version "2.16.0"

#(define ((alter-lv-tie-curve offsets) grob)
    (let ((coords (ly:semi-tie::calc-control-points grob)))
        (define (add-offsets coords offsets)
            (if (null? coords)
            '()
            (cons
                (cons (+ (caar coords) (car offsets))
                    (+ (cdar coords) (cadr offsets)))
                (add-offsets (cdr coords) (cddr offsets)))))
        (add-offsets coords offsets)))

xlv = \override LaissezVibrerTie #'before-line-breaking = #(lambda (grob)
        (set! (ly:grob-property grob 'control-points)
        (if (= UP (ly:grob-property grob 'direction))
            ((alter-lv-tie-curve '(0 0 0.75 0.7 2.25 0.7 3 0)) grob)
            ((alter-lv-tie-curve '(0 0 0.75 -0.7 2.25 -0.7 3 0)) grob))))

\relative c' {
  \xlv
  c1 <c d>\laissezVibrer c
}
