[patch] Do not use docbook's lineannotation except for @r

[Per Bothner]

The shipped version translates all of  @b, @i, @s, and @r to
<lineannotation>, when generating docbook.  This makes @b, @i, and @s
effectively be no-ops, which is wrong.

I think the right solution is to only emit lineannotation for @r,
and use the "default" result for the others.

        * makeinfo/cmds.c (cm_i, cm_b, cm_s): Do not use docbook's
        lineannotation - only use it in cm_r.

	lineannotation - only use it in cm_r.
