+ This function is mainly used under Windows (as under Unix we always get 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.
