That gives you a list of all entries in the tree, which (under /files)
are all files that Augeas knows about _and_ are present on your system
(e.g. you wouldn't see that it can handle Apt's sources.list)

You can get that list also by recursing through /augeas/files and
looking for entries that end in 'path' .. that will always be
'/files/FSPATH' where FSPATH is the path in the file system for the file
that is mapped at '/files/FSPATH'

The real list of files Augeas can handle is in internal data structures
(specifically in transform values defined by the modules) If that
information seems valuable, I could expose it in the /augeas hierarchy,
too
