This function is mainly used under Windows (as under Unix we always get the
- command line arguments as argc/argv anyhow) and so it tries to handle the
- Windows path names (separated by backslashes) correctly. For this it only
- considers that a backslash may be used to escape another backslash (but
- normally this is _not_ needed) or a quote but nothing else.
-
- In particular, to pass a single argument containing a space to the program
- it should be quoted:
-
- myprog.exe foo bar -> argc = 3, argv[1] = "foo", argv[2] = "bar"
- myprog.exe "foo bar" -> argc = 2, argv[1] = "foo bar"
-
- To pass an argument containing spaces and quotes, the latter should be
- escaped with a backslash:
-
- myprog.exe "foo \"bar\"" -> argc = 2, argv[1] = "foo "bar""
-
- This hopefully matches the conventions used by Explorer/command line
- interpreter under Windows. If not, this function should be fixed.
