Discussion:

29.12.6.5.9 [fs.path.decompose] p5 says:

> If root-directory is composed of slash name, slash is excluded from the returned string.

but the grammar says that root-directory is just slash so that makes no sense.

[Apr 2016 Issue updated to address the C++ Working Paper. Previously addressed File System TS]

Proposed resolution:

Change 29.12.6.5.9 [fs.path.decompose] as indicated:

>     path root_directory() const;

> > Returns: root-directory, if `pathname` includes root-directory, otherwise `path()`.

> > If root-directory is composed of slash name, slash is excluded from the returned string.
