    bin/sh               expand.c 
  Log:
  Instead of eating trailing newlines after inserting them into the
  output buffer, don't insert them at all.  This prevents a buffer
  *underrun* when the substitution consists completely of newlines
  (e.g. `echo`) and the byte before the source buffer to which p
  points is a '\n', in which case more characters would be removed
  from the output buffer than were inserted.
  
  This fixes certain port builds on sparc64.
