huuuh

is it a bug?? or a feature??

I made a test with the following directory structure:
./test/
./test/-r/
./test/1/
./test/2/
./test/3/

Then populated it with some files

echo "lala" > 1/1
echo "lala" > 2/1
echo "lala" > 3/1

Then i did:
$ grep "lala" *

1/1:lala
2/1:lala
3/1:lala
$

Then i renamed that directory

mv ./-r ./.-r

$ grep "lala" *
$

Nothing.

The problem comes from the bash * expansion that makes grep see that 
filename as an option. Is it a bash problem? Is it a grep problem?? 
Don't know...

Should it be reported to anyone?
