unnested_or_patterns can actually expand code (in text size)

[matthiaskrgr]

#![warn(clippy::unnested_or_patterns)]
pub enum E {
    A,
    B,
}


pub fn a(enm: &E) {
    match enm {
        &E::A | &E::B => {} 
    }
}


pub fn main() {}

clippy will suggest to use
&(E::A | E::B) instead of
&E::A | &E::B
this actually makes the code a bit bigger.
Is this intended?

57 |         Some(&b'e' | &b'E') => {
   |         ^^^^^^^^^^^^^^^^^^^

help: nest the patterns
   |
57 |         Some(&(b'e' | b'E')) => {
   |         ^^^^^^^^^^^^^^^^^^^^

warning: unnested or-patterns

Seems reasonable to ignore &.
