Subject: Use "progdlg_t *" rather than "void *" as the handle for a progress
 dialog box; that lets us do some type-checking, but we can still typedef it
 to an incompletely-defined structure to hide the implementation details from
 the caller.

Make "create_progress_dlg()" take, as an argument, the title to put in
the "stop the operation" button, and use "Stop" rather than "Cancel" if
stopping the operation doesn't undo all the work it's done.

Thaw the clist if we break out of a "read the file" operation, as we
freeze it before the operation.

Have the handler for the "delete" event on the progress dialog box
return FALSE, to let GTK+ know that it should, in fact, delete the
window.  ("delete" event handlers should return TRUE if the window
shouldn't actually be deleted, FALSE if it should; they should not
return "void".)
