The description of the required state before calling virtual member basic_streambuf<>::pbackfail requirements is inconsistent with the conditions described in 220.127.116.11.4 [lib.streambuf.pub.pback] where member sputbackc calls it. Specifically, the latter says it calls pbackfail if:
traits::eq(c,gptr()[-1]) is false
where pbackfail claims to require:
traits::eq(*gptr(),traits::to_char_type(c)) returns false
It appears that the pbackfail description is wrong.
In 18.104.22.168.4 [streambuf.virt.pback], paragraph 1, change:
Note deliberate reordering of arguments for clarity in addition to the correction of the argument value.
