Syntax error in convert-ly 2.1.34

[Peter Chubb]

Hi.

Version 2.1.34 of convert-ly appears broken.
I see:

This appears to be

     str = re.sub 
(r"(\\set)\s+)?(?P<context>(Score\.)?)breakAlignOrder\s*=\s*#'(?P<list>[^\)]+)",
                  r"\n\\override \g<context>BreakAlignment #'break-align-orders 
= "
             + "#(make-vector 3 '\g<list>)", str)

Which I suspect should be
      str = re.sub 
(r"(\\set\s+)?(?P<context>(Score\.)?)breakAlignOrder\s*=\s*#'(?P<list>[^\)]+)",
                      r"\n\\override \g<context>BreakAlignment
#'break-align-orders = "
                             + "#(make-vector 3 '\g<list>)", str)
