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.

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.)
