Subject: (Retracted by #8264)  More join() testing which was good because
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=7df053ec69e901392ae6352566832be0a6917cfe;p=p5sagit%2Fp5-mst-13.2.git

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