Sustaining to end of measure (to bar line)?

[Jesse Bye]

 I'm writing a piece of music where I'd like to sustain some notes to 
the end of a measure:

  \set tieWaitForNote = ##t
  \set Staff.pedalSustainStyle = #'bracket
  e,4~\sustainOn fis~ b~ <e, fis b cis>4~
  % 10
<e fis b cis>1\fermata\sustainOff

With the above code, the sustain bracket ends immediately after the 
final notes (e fis b cis). I'd like it to extend to the end of the 
measure (to the bar line). Is this possible? I had a similar issue 
previously extending a trill to the end of a measure, and was able to 
solve it by using " \override TrillSpanner #'to-barline = ##t ". Is 
there something similar that I can tweak for the sustain spanner?
