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 
']*>[^<]*|<(form|input).*?>|' | \
+   perl -E 'local $$/; my $$input=<>; $$input =~ 
s:]*>[^<]*\n*|<(form|input).*?>|\n*::gsm; print 
$$input;' | \

("$$" instead of "$" is needed even inside single quotes as this is
inside a Makefile where $ is a special character already.)

Regards, Axel

Thanks for the bug report! So pcregrep hasn't been ported (by
PCRE upstream) to libpcre2 either? *sigh*

The sole reason I use it over grep is that it supports multiline
matches. It though seems that grep might be able to do that — albeit
non-obviously — via "grep -Pzov", too.

Otherwise, I'll probably just use the original with "perl -E". It's
just the build system trying to remove any unwanted crap (multiline

Hi,

we want to get rid of pcre3 in trixie. As such unburden-home-dir's
Build-Depends on pcregrep dependency will become unsatisfiable.
