bug#13829: 24.2.93; delete-window different behaviour in gui and tty

[Leo Liu]

I was browsing emacs/src in a ssh session. I observed ggtags.el behaving
differently there.

Here is the recipe:

1. Install ggtags from GNU ELPA
2. cd emacs/src
3. Run in terminal: gtags¹
4. emacs buffer.c and moves to line 61 with point at the word 'buffer'
5. M-x ggtags-mode
6. M-.

In a GUI emacs you should have the frame with just one window showing
buffer.h.

In a TTY emacs you should have the frame having TWO windows showing
buffer.h and buffer.c.
