	   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"?

History expansion is purely textual excepting the cases of counting
arguments to the last command.  In that case, the line is split into
separate words in the same fashion as the shell, and that includes
quoted strings.

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.
