the file selection dialog.
Call gtk_file_chooser_set_do_overwrite_confirmation() in
file_selection_new() for FILE_SELECTION_SAVE file selection dialogs,
rather than doing it in the individual callers of file_selection_new().
Use gtk_dialog_set_alternative_button_order() in file_selection_new() to
set the alternative button order, rather than using #ifdefs.
Use file_selection_new() and file_selection_run() in the graph analysis
code. (We should clean up other code that uses file_selection_new() to
use file_selection_run(), and clean up other code that uses
gtk_file_chooser_dialog_new() to use file_selection_new() and
file_selection_run().)
