 OK. I suggest Vect!__open_old() and Vect_open_new() should initialize all
 file pointers to NULL and Vect_close() should close anything that is not
 NULL.

 These changes should IMHO first be done in trunk, then backported.

 ... on the first run on Windows when using the wxGUI. BTW, it '''does'''
 work for me just fine on Windows using the !TclTk GUI.

 IOW, if Vect_close() is called before the files are to be removed.
