Subject: [PATCH] config: store new variables with the internal representation
 of the section
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The section name should be stored in its case-sensitive variant when
we are adding a new variable. Use the internalize_section function to
do just that.
