[PATCH] A generic basic_filebuf::_M_underflow

[Pétur Runólfsson]

Hi,

This patch removes the specializations of basic_filebuf::_M_underflow
and adds a generic version, based on the old wchar_t specialization.

This naturally depends on my patch for cin being applied first,
otherwise things will break pretty badly.

Tested on linux on x86
