bpo-28166: Continue to read after Ctrl+C if SIGINT was ignored

[ValeriyaSinevich]

Do not break out of the reading loop if SIGINT was ignored or the handler doesn't raise an exception.

@ValeriyaSinevich The whitespace issue seems to be because of using tabs instead of spaces (which for some unknown reason VS still defaults to for C++...).

Replacing them with spaces (and ensuring indents of 4 spaces, which doesn't seem to be consistent in the existing code) should get you past that check.

@ValeriyaSinevich, please address @zooba's comments about the whitespace in order to pass the CI checks. Thanks!
