On-line documentation example about custom NIS maps may have an error, does it?

@(while

On Modifying Makefile Entries I believe there's an error in mentioning the ".time" make targets in the "all" rule example.
Furthermore, I also believe that nothing special must be done for the "auto_home" map as it's built-in handled by default.

Then, if I'm not mistaken (am I?), the online documentation should be corrected accordingly.

Furthermore, what's in step 4 is also wrong:

auto_direct.time: $(DIR)/auto_direct
 @(while read L; do echo $$L; done < $(DIR)/auto_direct
 $(CHKPIPE)) | \ (sed -e "/^#/d" -e "s/#.*$$//" -e "/^ *$$/d"
 $(CHKPIPE)) | \ $(MAKEDBM) - $(YPDBDIR)/$(DOM)/auto_direct;
 @touch auto_direct.time;
 @echo "updated auto_direct";
