Bug#1026986: console-setup: "Dead" keys do not work for Greek keyboard layout in tty

I never imagined that for dead keys there is code in the kernel.

There is a workaround then.
The Microsoft Windows workaround:

Press key combination Shift-w (dead key for ΅)
Press key y or i to get characters ΰ or ΐ.

These characters are very useful in the Greek language.
Also the implementation with the Shift-w key combination does not
break anything as:
key s gives char σ
key combination Shift-s gives char Σ
key w gives char ς
key combination Shift-w gives char Σ again (this duplication does not
exist on Microsoft Windows as it is a dead key)

Advantages:
- Very useful Greek keyboard characters will be implemented.
Everything is better than nothing.
- Only one dead key, as the kernel permits.
- It will not create significant confusion for users because it is the
same keyboard layout as the equivalent of Microsoft Windows.

Disadvantages:
- X has another key combination: ; Shift-; y instead of Shit-w y. This
will be a bit confusing for users, but consider that now these useful
characters are not EVEN available in tty!

Any thoughts?
