Default history does not work with Lisp regexps

[David Kastrup <dak@gnu.org>]

Ok, here is the gist of a bug report.  I have not sent it to the bug
list since I don't need any review for getting this classified as
something we need to do something about.

Basically this boils down to the question: what do we enter in the
history list, the compiled Lisp expression or a string?  If we enter a
string, then we need to go through compilation again in case somebody
just hits RET in order to get the defaults.

Any objections?
