Nope, even much simpler cases fail to remove just a substring from a single line: ~ → printf 'foo\ngnarz\nbar\n' | fgrep -voz nar ~ → printf 'foo\ngnarz\nbar\n' | fgrep -ov nar etc. > Otherwise, I'll probably just use the original with "perl -E".

The following change works and produces byte for byte the identical result as "pcregrep -Mv", it's just a bit longer: - pcregrep -Mv '<script[^>]*>[^<]*</script>|<(form|input).*?>|</form>' | \ + perl -E 'local $$/; my $$input=<>; $$input =~ s:<script[^>]*>[^<]*</script>\n*|<(form|input).*?>|</form>\n*::gsm; print $$input;' | \ ("$$" instead of "$" is needed even inside single quotes as this is inside a Makefile where $ is a special character already.)
