Not bothering to discard a duplicate syntax -- selecting simply the 

last-defined one.  This addresses Savannah bug #47303.

* src/rcfile.c (parse_syntax), src/color.c (color_update): Don't
bother discarding a duplicate syntax (it's too rare, saves little
memory, and freeing it properly would cost even more code), just
select the last-defined one. This addresses Savannah bug #47303.
2016-02-29 Benno Schulenberg <bensberg@justemail.net>
* src/nano.h, src/rcfile.c, src/color.c: Rename a struct member.
* src/rcfile.c (parse_rcfile): Don't allocate a struct for the "none"
