 A second hole is that the last slash will be trimmed from the path, but one could still use ".//" and it would get past this function, and
 possibly be interpreted by the Boost file functions as "the current directory". Iow, both of these checks need to be iterative, not one-time.

|   C. '.' as the whole path															 |
