>Description:
	awk produces incorrect output
>How-To-Repeat:
	Given the script below:

#!/bin/sh
(cat $1; echo x: xmap.o) | \
        sed 's/\.c/.o/g' | \
        awk '-F[[:space:]]*:[[:space:]]*' \
            'BEGIN {printf "all: $(ALL)\n$(ALL):"} \
                   {printf " %s",$2} \
             END   {printf "\n\tar cruvs $(ALL) \$?\n\n"}
             END   {printf "xmap.o: xmap.c xmap.h\n"}
             END   {printf "\n"}
             END   {printf "xmap.h::\n"}
             END   {printf "\t./makexmap.sh modules.map > xmap.h\n"}'


And the following sample input file (argv[1] to the script) contents:

admin.so:               blocked.c exempt.c licenses.c


The following (incorrect) output is produced (see the end of the 2nd line):

all: $(ALL)
$(ALL): blocked.o exempt.o licenses.o x
        ar cruvs $(ALL) $?

xmap.o: xmap.c xmap.h

xmap.h::
        ./makexmap.sh modules.map > xmap.h


If the "x:" in the first line of the script is replaced with "xy:"
a different incorrect output is produced:

all: $(ALL)
$(ALL): blocked.o exempt.o licenses.o
        ar cruvs $(ALL) $?

xmap.o: xmap.c xmap.h

xmap.h::
        ./makexmap.sh modules.map > xmap.h


And using "xyz:" a third incorrect output is produced:

all: $(ALL)
$(ALL): blocked.o exempt.o licenses.o n.so
        ar cruvs $(ALL) $?

xmap.o: xmap.c xmap.h

xmap.h::
        ./makexmap.sh modules.map > xmap.h


Finally, using a long enough, say "wxyz:" produces correct
output:

all: $(ALL)
$(ALL): blocked.o exempt.o licenses.o xmap.o
        ar cruvs $(ALL) $?

xmap.o: xmap.c xmap.h

xmap.h::
        ./makexmap.sh modules.map > xmap.h
