Marc and me, we discussed this some time ago and decided not to
provide that functionality.
It would make things more complicated for the user and I think it is a
rarely needed feature.

BTW, you can change the SpanBar at line-end/begin even with 2.14.2
using some scheme:

\version "2.14.2"

#(define (change-span-bar-at-line-begin g)
  (if (and (ly:item? g)
           (equal? (ly:item-break-dir g) RIGHT))
      (ly:grob-set-property! g 'glyph-name ":")))

cSp = \once\override Score.SpanBar #'after-line-breaking =
#change-span-bar-at-line-begin


\new StaffGroup <<
\new Staff \relative c' { c1 \bar ":|:" \cSp \break d }
\new Staff \relative c' { c1 \break d }
>>
