BTW, I did confirm that this changeset does as intended by doing an fprintf(stderr,...) inside the terminal destructor.

The attached changeset is a small patch which will store the STDERR_FILENO pipe so that it may be restored at exit. This will allow any errors occurring at exit to be posted in a terminal if that is where Octave was launched from. Otherwise any exit error messages get displayed in the GUI terminal window and are gone unnoticed along with the closing of the Qt main window.

This isn't necessarily a bug, but in some sense it helps to uncover bugs. For example, I was finding a bug at exit that was going unnoticed. Turns out in the past couple weeks it was fixed by someone else. (The _terminal was being deleted twice.) Nevertheless, the attached change would have been helpful from the original onset of the bug.
