 Delete hack when takeDirectory returns ""

 Summary:
 Since commits 8fe1f8 and bb6731 in the filepath packages (ticket #2034,
 closed
 in 2010), takeDirectory "foo" returns ".", and not "", so this check is no
 longer needed.

 Other commits:
 * Remove trailing whitespace
 * Update comments for #2278
