Good question. The exit code is 0xc000013a if the signal was generated by hitting Ctrl-C (tested with 'git --no-pager log'), but it is 3 if the signal was "generated" by 'raise(SIGINT)'. The implementation of the latter just calls _exit(3) (same for other deadly signals). Wow!

Windows's signal() does return EINVAL; appearently, we never check the return code. :-P
