Subject: S_utf16_textfilter() needs FILTER_DATA() to get the filter's state SV.
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=89655c2e76bb18695d13f2accf9932e415907f92;p=p5sagit%2Fp5-mst-13.2.git

S_utf16_textfilter() needs FILTER_DATA() to get the filter's state SV.

aa6dbd607b0a3d8a wrongly assumed that the filter's state SV was the SV passed
in as an argument to the filter read function.
