Fix memory clobbering bug in _fullpath()...

If part of the path were removed (ie: "//", "/./", or "/../"), it's possible
that the outer loop would extend past the string into uninitialized memory
where it could potentially corrupt things.

This was HIGHLY unlikely as it would stop at the first '/' and only corrupt
memory in the presence of the previously mentioned patterns.
