in man it's being said,
-I RE --ignore-matching-lines=RE
Ignore changes whose lines all match RE.
I read man grep and it seems there are two sets of RE, extended and basic. But
it's not mensioned in diff(1) wheather or not diff(1) takes extended or basic
RE. I am using Debian so it should be gnu diff.
If it's not mentioned, it possibly uses basic regular expressions.
try:
$ diff -I '/\* \$Id.*\$ \*/' header.inc.php empty
