  Log:
  SVN rev 196634 on 2009-08-28 22:41:25Z by jilles
  
  sh: Fix crash with empty functions (f() { }) introduced in r196483
  
  Empty pairs of braces are represented by a NULL node pointer, just like
  empty lines at the top level.
  
  Support for empty pairs of braces may be removed later. They make the code
  more complex, have inconsistent behaviour (may or may not change $?), are
  not specified by POSIX and are not allowed by some other shells like bash,
  dash and ksh93.
