POSIX requires the useless question. That being said, the question could
be omitted in the case you describe, if POSIXLY_CORRECT is not specified.

Did you consider that more than one terminal can be open, and at the second=
 terminal, "b" could be renamed before replying to the mv command?

User thinks well why didn't you check before uselessly asking me?

Full story:
$ mkdir a
$ touch b
mv: overwrite 'b'? y
mv: cannot overwrite non-directory 'b' with directory 'a'
$ \mv a b
mv: cannot overwrite non-directory 'b' with directory 'a'
$ alias
alias mv=3D'mv -i'

So even if -i is in effect, please do the check before asking users
useless questions.

$ mv a b
mv: overwrite 'b'? y
mv: cannot overwrite non-directory 'b' with directory 'a'

User thinks well why didn't you check before uselessly asking me?

Full story:
$ mkdir a
$ touch b
mv: overwrite 'b'? y
mv: cannot overwrite non-directory 'b' with directory 'a'
$ \mv a b
mv: cannot overwrite non-directory 'b' with directory 'a'
$ alias
alias mv='mv -i'

So even if -i is in effect, please do the check before asking users
useless questions.
