Grep -r with no files should imply ./

[Tom Felker]

Hi,

When I mean "grep -r foo ." but type "grep -r foo", grep just waits for input 
until I notice my disk not chugging and correct my mistake: the --recursive 
option has no effect unless there are input files.  Since I usually mean to 
search the current directory, I think --recursive should cause the input to 
default to . instead of stdin.

If someone applies this, it'll save me a lot of typing.  Please cc: me.

Thanks,
Tom Felker
