Subject: [PATCH 38/79] CHILD: Pass information about logger to children
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Variables debug_to_file or debug_to_stderr were not set
because back-end already user parameter --logger=%s.
And therefore logs were not sent to files.

It could only work in case of direct usage of --debug-to-files in back-end via
command configuration option.

Resolves:
