Error in multiple target eaxmple

[Jimall]

I think there is an error in multiple-targets chapter(https://makefiletutorial.com/#multiple-targets), miss : after f1.o and f2.o, here is the screenshot:

should be:

# f1.o:
#	 echo $@
# f2.o:
#	 echo $@

and I think this will be more clear to show When there are multiple targets for a rule, the commands will be run for each target and the meaning of $@:

# f1.o:
#	 echo f1.o
# f2.o:
#	 echo f2.o
