An isearch command that wraps?

[Lloyd Zusman <ljz@xxxxxxxxxx>]

Has anyone written an isearch command that wraps, sort of like the
isearch does in Gnu Emacs?

The following scenario illustrates what I mean:

     Ctrl-s (start isearch)

     Enter search string - jed incrementally finds the matching
                           string as characters are entered

     Ctrl-s - jed finds next occurrence of matching string

     Ctrl-s - jed finds next occurrence of matching string

     ... etc. ...

     Ctrl-s - finally, there is no match: jed prints a message
              indicating this fact

 *** Ctrl-s - the search wraps to the top of the buffer, and the
              first match is found again

     ... etc. ...

The key step in this process is the one that I marked with three
asterisks ("***").  In other words, once a match is not found, if the
isearch invocation key sequence is invoked again at that point, the
search wraps to the top of the buffer and repeats.

I'd like the same sort of thing to occur with a reverse isearch.

I vaguely remember asking about this here a year or so ago and someone
pointing me to some code that does something similar to this.  But
unfortunately, I can't find that post nor the code that was descibed to
me.

Thanks in advance for any pointers you folks can give me to some code
that will do this.
