Function arg_split

IPython/utils/_process_win32.py:179–198

Split a command line's arguments in a shell-like manner. This is a special version for windows that use a ctypes call to CommandLineToArgvW to do the argv splitting. The posix parameter is ignored. If strict=False, process_common.arg_split(...strict=False) is used i
