	* include/bits/streambuf_iterator.h (class istreambuf_iterator):
	Consistently use _M_c to cache the current char, i.e., not only
	when operator++(int) is involved; change _M_c to mutable.
	(_M_get()): Always save the return value of _M_sbuf->sgetc() into
	_M_c.
	* testsuite/22_locale/time_get/get_monthname/char/1.cc: Fix
	(long standing) typo.
	* testsuite/22_locale/time_get/get_monthname/wchar_t/1.cc: Likewise.
	* testsuite/22_locale/time_get/get_weekday/char/1.cc: Likewise.
