Subject: (Retracted by #8264)  More join() testing which was good because
X-Git-Tag: accepted/trunk/20130322.191538~33227
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7df053ec69e901392ae6352566832be0a6917cfe;p=platform%2Fupstream%2Fperl.git

(Retracted by #8264)  More join() testing which was good because
it revealed a bug in #8248 (the UTF8_EIGHT_BIT_LO() was wrong).
