Some sites randomize their casing on URIs which would cause GM to fail to inject a script. Both virtual server names as well as document paths.
It would be helpful to support some sort of /rex/i to address these situations.
I'd also be interested to know what happens when an invalid Regular Expression is encountered (say an unterminated character class).
This also leads to @match portability... Are we going to add a very helpful feature just to the 'cludes and introduce the "stone age" pattern matching only with @match?
Oops. Missed quotes around the i.
Add quotes around 'ignore case' regexp flag.
