It's already handled in st.c (in kpress()). It should be working
(without shift) without this. Are you sure you compiled the terminfo
entry?

Ok, so I've gone through rxvt-unicode/xterm source code (ugh):

rxvt: arrow keys \e[x with x = ABCD
rxvt: shift + arrow keys \e[x with x = abcd
xterm in emacs: arrows \eOx with x = ABCD
xterm !in emacs: arrows \e[x with x = ABCD
xterm in&out emacs: shift + arrow \e[1;2x with x = ABCD (wtf)

I've made some tests and guess what? None of these work when outputed
by st unless you change TNAME to the corresponding terminal.
This means that the behaviour of emacs is, as usual, determined by the
terminfo entry... and I have no idea where. *sigh*

So if anyone wants to help dump a terminfo entry like this

  $ infocmp <terminal name>

see terminfo(5) for a description of each capability and try to find
something related to this problem.
