2014-04-08 Benno Schulenberg <bensberg@justemail.net>
* src/rcfile.c (parse_binding): Melt the binding and unbinding code,
which are very similar, into a single function.
2014-04-07 Benno Schulenberg <bensberg@justemail.net>
* src/{proto.h,global.c,text.c}: Keep a pointer to the Uncut item in
the functions list, to be able to change its description to Unjustify
