Vocabulary
io.pathnames

Inputs and outputs

path	a pathname string
path'	a new pathname string

Word description
Outputs a path where none of the path components are symlinks. This word is useful for determining the actual path on disk where a file is stored; the root of this absolute path is a mount point in the file-system.

Notes
Most code should not need to call this word except in very special circumstances. One use case is finding the actual file-system on which a file is stored.
