Yes, %b is a hard case, neither way makes a lot of sense to use the
precision, certainly truncating the input string half way through an
escape sequence would be absurd, so if the precision needs to do
anything at all, having it apply to the expanded string makes more
sense than having it apply to the input. Using the precision with a
%b expansion probably indicates a user who isn't really thinking though.
%q however is different, there applying the precision to the quoted
string is ludicrous (but easy to implement), whereas applying it to
the input can be useful (but means more work).
