	      However, notice that it says ls" not found.  The quote
      stripping is not done correctly.

   Compared to what?  Do you have an example of history expansion that
   works "correctly"?

   In the case of searching for a string with `!string' quoting is
   unrelated.  However, I concede that the above example stresses the
   inadequacies of !-style history expansion in general.  Perhaps a special
   case could be made for just this circumstance.

Compared to the csh example that Rob mailed me.  Csh stripped the
quotes.  Maybe it is better to do ! expansion on whitespaced words,
much the same a tilde expansion.  Instead of passing the entire line
off to history, just pass the "proper" word.  Programs other than bash
can choose to hand entire lines off to history.
