Subject: [PATCH 19/26] xapcmd: use "print STDERR" for progress reporting
Date: Thu, 23 May 2019 09:36:57 +0000
Message-ID: <20190523093704.18367-20-e@80x24.org> (raw)
In-Reply-To: <20190523093704.18367-1-e@80x24.org>

`warn' is reserved for actual warnings, as it respects
$SIG{__WARN__} and we rely on that override to print
message context information when we are indexing.
