Can't use "-" in patterns #38

...even though it's legal to have package names with it.

Here's a fix, in com.tonicsystems.jarjar.Wildcard:

    private static boolean checkIdentifierChars(String expr, String extra) {
        for (int i = 0, len = expr.length(); i < len; i++) {
            char c = expr.charAt(i);
            if (extra.indexOf(c) >= 0)
                continue;
            if (c == '-')
                continue;
            if (!Character.isJavaIdentifierPart(c))
                return false;
        }
        return true;
    }

Now, I know a "-" isn't legal generally in Java, but there are definitely JNI
packages (notably JNI) that use this. So it goes.

This fix was necessary for the Jython project, which uses JarJar.
