Well the question is whether this should be worded as
ecryptfs-setup-{private,confidential} issue, or more generic issue
affecting various ecryptfs-* command line utilities, that only accept
passwords as command line arguments (i.e. no interactive prompt).  So
even though there's not ecryptfs-setup-* script to fix in older
versions, steps done by ecryptfs-setup-* are likely to be performed by
the user manually, resulting in the same risk of leak as with helper
script.  Or do I miss anything?
