This breaks Posix:
The following options shall be supported by the implementation:
-f Do not prompt for confirmation if the destination path
exists. Any previous occurrences of the -i option shall
be ignored.
-i Prompt for confirmation if the destination path exists.
Any previous occurrences of the -f option shall be
ignored.
Specifying more than one of the -f or -i options shall not be considered
an error. The last option specified shall determine mv's behavior.

4.43.5.1 Standard Input
Used to read an input line in response to each prompt specified in
Standard Error. 4.43.6.2. Otherwise, the standard input shall not be
used.
So it doesn't look that Posix would allow a special treatment of
terminal devices.
