An asterisk glob will never "expand" to zero length, but will rather
leave the * as is...

russell at stratus:~/tmp$ touch ubuntu
russell at stratus:~/tmp$ echo *buntu

*Ubuntu

I promise I didn't cheat and create a file called "*Ubuntu" ;)

Of course, an asterisk glob which was not expanded means that the file
doesn't exist and your -f will be false anyways.
