OK, that's how I read it too. I'll work on making it behave with hex
input and not worry about the output, which takes care of itself.

I also notice that the following has trouble:

thomas=# select bit '1010';
ERROR: bit string length does not match type bit(1)

which is similar to the very recent problem with fixed-length character
strings. I've got patches to fix this one too.
