You're welcome.  SXEmacs which I've never explored satisfied my
curiosity. ;-)

It is platform-dependent, isn't it?  In the Fedora Core 6 system,
I didn't get a non-nil value using 22.1.6--patch-119 and this form:

(string-match
 "[^x]"
 (mapconcat #'char-to-string (make-string 3200000 ?x) ""))
 => nil

And I also got:

(length (mapconcat #'char-to-string (make-string 3200000 ?x) ""))
 => 3200000

Anyway I've removed such one which forces heavy labor to (S)XEmacs.

I'll install the new version.  Thanks.
