Subject: [PATCH] doc: mention that df -a includes duplicate file systems
* src/df.c (usage): Mention that duplicate file systems are shown
with this option, not just dummy file systems.
* doc/coreutils.texi (df invocation): For the --all option, expand
on the class of normally suppressed mount entries that it includes.
