Hi
I'm a bit of a regular expression noob, so I'm not sure if this is a bug
or if I'm just missing something about how grep works.
Here's a demo of the issue I have encountered:
> bash$ rm empty
> bash$ touch empty
> bash$ # I am expecting a match, so grep should return 0.
> bash$ grep '^$' empt

bash$ grep '^$' empty
bash$ echo $?
Grep looks for lines that contain matches. An empty file has no lines, so it
cannot possibly contain any matches for any regular expression.
