Weird behavior with alternivies. #108

Description

@lolbinarycat

I have the following files:
main.go:

package main

func main() {
	p := &Parser{Buffer:"test"}
	p.Init()
	err := p.Parse()
	if err != nil {panic(err)}
}

grammer.peg

package main

type Parser Peg {}

Rule <- ( "t"  / "test" ) !. 

running peg grammar.go && go run . results in the following error:

panic: 
parse error near Unknown (line 1 symbol 1 - line 1 symbol 1):
""


goroutine 1 [running]:
main.main()
        /home/binarycat/go/src/github.com/lolbinarycat/peg-bug/main.go:7 +0xb4
exit status 2

This doesn't seem intended, as it makes lots of things much harder to do. If it was intended, then this behavior should be clarified on the readme.
