bug#54027: Wishlist: Support full CSI u specification for terminal input

[Alex Hutcheson]

Was a consensus ever reached on this? 

Stefan's patch looks like it does what I was asking for. 

It would be great if we could also handle the `ESC [ ... u` versions, because xterm will emit them in 

some configurations, and iTerm2 can only emit those.

The above just reads to "NN;MM" part of the escape sequence which
encodes in decimal the Unicode code point MM of the character and the
4bit encoded NN of the modifiers shift, alt, control, and meta.
