Issue for The Wildcard Function (Section 4.2.3)

I got the opposite result, "wrong" can be printed while "objects" can't be printed.

echo *.o

This output is correct! echo *.o is not what you want -- you want nothing to be printed because searching for files that end in .o don't yield any files, if there are no matching files. I've revamped some of the wildcard examples that hopefully describe this better
