[ 2014-02-11 Issaquah: NAD. LWG/SG-3 reviewed each function and return type, and found that since they have different functionality different return types are warranted. create_directory has an inconsistent return type between the synopsis and the description. This has subsequently been corrected editorially. ]

Addresses: filesys.ts

It is unclear why copy, copy_file and copy_symlink have different return types, and why the attribute-version of create_directory has a different return type than the create_directory that takes no attributes. The status/error reporting in these functions seems inconsistent.

Resolution:

Make the status/error reporting consistent or add a note explaining why it's different.
