Feature request: write-file dialog in w32

[Eduardo Muñoz]

The function write-file when invoked with the mouse shows an
*open* file dialog to get the name of the file to save. It
would be nice to use a *save* file dialog.

It is not difficult to change the function 'x-file-dialog'
in w32fns.c to use a save dialog (using a fifth optional
argument save_dialog):

....
      if (!NILP (mustmatch))
        file_details.Flags |= OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST;

      BOOL open_dialog_result;

      if (NILP (save_dialog))
          open_dialog_result = GetOpenFileName (&file_details);
      else
          open_dialog_result = GetSaveFileName (&file_details);
      
      if (open_dialog_result)
        {
....

But I see that a number of changes must be made to other
functions to keep consistency (read-file-name, motif, etc). 
So I leave the decission (and the work ;) to the emacs
maintainers. 

Saludos
