Subject: Fix a syntax incompatibility introduced by the // operator.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=7ce6e6b9b330bcb2a1d155869572dcbf97a67971;p=p5sagit%2Fp5-mst-13.2.git

Fix a syntax incompatibility introduced by the // operator.
(Note that C<print $fh //> is still a syntax error, it
wasn't with perl 5.8.0.)
