I checked if the test using IPC::Run::signal can work on Windows, and
confirmed that this didn't work because sending SIGINT caused to
terminate the test itself. Here is the results;

t/001_basic.pl ........... ok    
t/010_tab_completion.pl .. skipped: readline is not supported by this build    
t/020_cancel.pl .......... Terminating on signal SIGINT(2)

Therefore, this test should be skipped on Windows.

I attached the update patch. I removed the incorrect comments and
unnecessary lines. Also,  I rewrote the test to use "skip_all" instead
of SKIP because we skip the whole test rather than a part of it.
