4bc5697341f1eda3b20c16dcf173948b2d1bd5c8 libstdc++: Fix std::format of chrono::local_days with {} [PR120293]
Formatting of chrono::local_days with an empty chrono-specs should be
equivalent to inserting it into an ostream, which should use the
overload for inserting chrono::sys_days into an ostream. The
implementation of empty chrono-specs in _M_format_to_ostream takes some
short cuts, and that wasn't being done correctly for chrono::local_days.
libstdc++-v3/ChangeLog:

* include/bits/chrono_io.h (_M_format_to_ostream): Add special
