rustdoc converts byte literal discriminants into decimal numbers

For some code that generates my command prompt, I use a single ASCII character for the discriminant of an enum:

pub enum Permissions {
    Guest = b'%',
    User = b'$',
    System = b'@',
    Absolute = b'#',
}

However, rustdoc displays this as:

pub enum Permissions {
    Guest = 37,
    User = 36,
    System = 64,
    Absolute = 35,
}

Personally, I think that rustdoc should try to display the literal as it was originally written, rather than converting it to a plain integer.
