Matching fails if there are more than 10 OR's ( | symbol ) in the regex

[jonimake]

Not much else to say. The following piece of code will fail:
assert!(Regex::new(r"1|2|3|4|5|6|7|8|9|10|int").unwrap().is_match("int")); //fails

While this won't:
assert!(Regex::new(r"1|2|3|4|5|6|7|8|9|int").unwrap().is_match("int"));

Edit: this is with 0.1.58 and rust 1.7

This was fixed in my literal detection refactor: 31a317e

I added a regression test in: 49577de

The old code was detecting the following as prefixes: '1', '2', '3', '4', '5', '6', '7', '8', '9'. Which is wrong, because it doesn't include int.
