But.  But ... we can't get the string before it's metafied in the first 
place? How is it possible
for it to be metafied before 'it' exists? If I can have a meta-fried 
egg, surely at some point there
was a raw egg? I was looking in hist.c, because the one place where 
things seem to be
stored 'literally' is in .histfile.

The Tao of zsh is a deep thing.

But somehow I just can't get anything to print if interactive.  I've got 
lots of feedback
if adding " puts("Hi. This is line xxx of file xxx")  " ... sort of 
things in the code
when  running a script, but if interactive nothing ever shows:

//    if (isset(VERBOSE)) {
     /* Output the whole line read so far. */
     zputs(ingetcline, stderr);
     fflush(stderr);
  //   }

... nothing doing, no output. I tried it from console too. Nothing. Is 
the xterm somehow
interfering?
