That's because -i is equivalent to --reply=query (as mentioned in --help),
and since you specify --reply=no after -i,
the --reply=no takes precedence.
The --reply=S option was added to ensure that this use of `mv'
(note the absence of a -i option)
touch a b; chmod u-w b; mv a b
could be made to do its job without prompting the user.
Without an option like --reply=yes, the above would prompt
the user with e.g., `mv: overwrite `b', overriding mode 0444?
Obviously, the descriptions (both --help and info) could be improved.
Corrections welcomed. Though maybe the whole --reply=S addition
deserves to be rethought.
