sysutils/logwatch: Need to patch very first line of a script fails, dunno why

Hi,

I am preparing for the upcoming logwatch-7.13 release, and ran into an issue I can't understand.

I do want to patch the logwatch.pl script by providing a 'files/patch-scripts_logwatch.pl' which starts as follows:

	--- scripts/logwatch.pl.orig    2025-07-18 18:21:47 UTC
	+++ scripts/logwatch.pl
	@@ -1,4 +1,4 @@
	-#!/usr/bin/perl -w
	+#!/usr/local/bin/perl -w
	 use strict;
	 ##########################################################################
	 ##########################################################################

	[followed by 17 other hunks]


Using "poudriere testport … sysutils/logwatch" I get:

	=======================<phase: patch          >============================
	===== env: DEVELOPER_MODE=yes DEVELOPER=1 STRICT_DEPENDS=yes USER=root UID=0 GID=0
	===>  Patching for logwatch-7.13

	===>  FAILED Applying FreeBSD patch-scripts_logwatch.pl
	===> FAILED to apply cleanly FreeBSD patch(es)  patch-scripts_logwatch.pl
	*** Error code 1

	Stop.


But: If I do apply that very same patch by 'patch < files/patch-scripts_logwatch.pl' at the appropriate location, all 18 hunks are applied successfully.


Can you help me to understand how to fix this?


Thanks in advance and regards,
Michael
