> Omitting it from sys.path in that case makes sense to me, but I'm not sure what sys.argv[0] should be set to.

I propose to use ".". It would be consistent with platforms which doesn't implement realpath:

    if (have_module_arg) {
        #if defined(HAVE_REALPATH) || defined(MS_WINDOWS)
            _Py_wgetcwd(fullpath, Py_ARRAY_LENGTH(fullpath));
            argv0 = fullpath;
            n = wcslen(argv0);
            argv0 = L".";
            n = 1;

And it defers the error handler to later. Example of Python 3 running in a removed directory:

$ python3
Python 3.7.2 (default, Jan 16 2019, 19:49:22) 
>>> import os
>>> os.getcwd()
FileNotFoundError: [Errno 2] No such file or directory

>>> os.path.abspath('.')
Traceback (most recent call last):
  File "/usr/lib64/python3.7/", line 383, in abspath
    cwd = os.getcwd()
FileNotFoundError: [Errno 2] No such file or directory

I would prefer "." than "-m".
