        with a -current make, building in src/external/mit/xorg/include/xproto
        fails with a sed error:

        nbsed: 1: "s/#undef NARROWPROTO/#d ...": newline can not be used as a 
string delimiter

        this is the makefile constrct:

Xfuncproto.h: Xfuncproto.h.in
        ${TOOL_SED} 's/#undef NARROWPROTO/#define NARROWPROTO/; \
                s/#undef FUNCPROTO/#define FUNCPROTO 15/' \
                < ${.ALLSRC} > ${.TARGET}

        and the makefile is at almost 6 years old.  i suspect the problem
        is the tabs in the continued line are now being passed through?

>How-To-Repeat:

        ./build.sh -x

>Fix:

        cvs up -D '3 days ago' src/usr.bin/make aka 0600 UTC august 21.
