        * src/color.c (set_colorpairs): Improve comments and rename vars.
        * src/files.c (read_line): Chop a superfluous bool -- 'prevnode' being
        NULL is enough indication that the first line is being read.
+       * src/files.c (switch_to_prevnext_buffer): Tweak comment and var name.

        * doc/syntax/Makefile.am: Add missing autoconf and nftables syntaxes.
