 * e_shell_run_save_dialog:
 * @shell: an #EShell
 * @title: file chooser dialog title
 * @customize_func: optional dialog customization function
 * @customize_data: optional data to pass to @customize_func
 *
 * Runs a #GtkFileChooserDialog in save mode with the given title and
 * returns the selected #GFile.  It automatically remembers the selected
 * folder.  If @customize_func is provided, the function is called just
 * prior to running the dialog (the file chooser is the first argument,
 * @customize_data is the second).  If the user cancels the dialog the
 * function will return %NULL.
 *
 * Returns: the #GFile to save to, or %NULL
