Subject: (process_regexp): Update CURRENT_LINE only if
X-Git-Tag: TEXTUTILS-1_19q~111
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d3f6a66654c917d07878257cb3c9391f9e85694;p=thirdparty%2Fcoreutils.git

(process_regexp): Update CURRENT_LINE only if
the new value would be larger.  This avoids the infinite loop
otherwise provoked by situations like this:
printf "\na\n" | csplit - '/a/-1' '{*}'
