Fixes #14 : '&' as arguments separator.

14

I guess that ; wasn't recognized as separator so arguments has broken or ; has unexpectedly and weirdly escaped.

After replaced it with &, it works. But I am not sure using & as argument separator will not cause any side effects.

Taking this on faith!

Would be great if you could add tests that fail before and succeed with this.
