Checks whether this has the prefix specified by prefix.
In other words, if the names of initial elements of this's pathname match prefix. Only
full pathname elements are matched, so a path like /foo is not considered a prefix of /foobar, only of /foo/bar.
This call does no I/O, as it works purely on names. As such it can sometimes return false
even if this is inside a prefix (from a filesystem point of view), because the prefix of
this is an alias of prefix.
