----------------------------------------------------------+-----------------
 Currently, a path that ends with a slash (or backslash on Windows) is
 treated as if it had an invisible "." at the end. For example,
 filename("/usr/") returns ".", and iterating over path("/usr/") produces
 the elements "/", "usr", and ".".

 I think this is a design error, because it leads to unexpected behaviors.
 For example, create_directories("foo/") fails even though the directory
 "foo" is successfully created, because the code tries to conclude by
 creating ".", which makes no sense and obviously will fail.

 I think the effect of ending a path with a slash should simply be that the
 final element (preceding the slash) is considered a directory name, not a
 filename. Therefore filename("foo/") should return an empty string, and
 has_filename("foo/") should return false. Most other operations, however,
 should act as if the slash simply wasn't there. Iterating over
 path("/usr/bin/"), for example, should return the elements "/", "usr", and
 "bin", and create_directories("foo/") should behave exactly the same as
 create_directories("foo").
