compatible with cxxopt.

in https://github.com/jarro2783/cxxopts/blob/v3.2.1/include/cxxopts.hpp#L1011-L1018

it checks the (!in),  if we read after reaching EOF,  the !in will be true
which results a incorrect_argument_type exception thrown.

we should be very careful to avoid read after reaching eof.
