%#b format: bug?

Watch this:

    printf "%#o\n", 181
    0265

    printf "%#x\n", 181
    0xb5

But 

    printf "%#b\n", 181
    010110101

I should have expected 

    0b10110101

for that one.  And given this:

    printf "%#X\n", 181
    0XB5

This surprises me:

    printf "%#B\n", 181
    %#B

However, both 0X and 0x are legal numeric prefixes, but only 0b are,
so perhaps I should be less surprised.
