shorter braces in 2.9.26?

[Marcus Macauley]

Is it just me, or have the braces on PianoStaff and GrandStaff suddently  
become shorter in 2.9.26?

I know LilypondTool (for jEdit) can sometimes display PDF files a little  
bit differently (braces shifted, dashed lines with longer dashes), but the  
following file gives me shortened (i.e. not as tall) braces in Xpdf 3 and  
Adobe Reader 7 (for Linux) as well:

\version "2.9.26"
<<
  \new GrandStaff
  <<
    \new Staff {c'}
    \new Staff {\clef bass c}
  >>
  \new PianoStaff
  <<
    \new Staff {c'}
    \new Staff {\clef bass c}
  >>
