Added guard to split not to get out of bounds exception when testing

[rogersm]

In the current test code we're accessing the splitted slice without checking if split returned a slice long enough.

    s := strings.Split(c, ";")
    if s[1] != " Path=/foo/bar/bat" {
	t.Error("Error writing path with options:", s[1])
    }

This patch checks the len of s is enough to access s[1]
