* include/std/std_istream.h (ignore(streamsize __n = 1,
int_type __delim = traits_type::eof())): Split into...
(ignore(), ignore(streamsize __n), ignore(streamsize __n,
int_type __delim)): The first two can be much more simpler
and efficient than the fully general case; also, the last
two can take advantage of the same mechanism already used
for getline.
* include/bits/istream.tcc (ignore(streamsize __n = 1,
int_type __delim = traits_type::eof()): Remove.
(ignore(), ignore(streamsize __n), ignore(streamsize __n,
