  Modified files:
    bin/sh               output.c 
  Log:
  Replace a home-grown printf() clone with a fwopen() wrapper around
  libc's vfprintf() that writes to a `struct output' instead of a file.
  
  Print empty quotes ('') when an empty string is passed to outqstr().
  This makes a difference for the trap builtin, where after "trap '' 0" we
  printed "trap -- quit".  This is wrong, because an empty action means to reset
  the action to the default.  A side effect of this commit is that empty
  variables are now printed as "variable=''" instead of just "variable=".
