	Partially add back in "support REP (repeat) escape sequence"

	Add the functionality back in for xterm compatibility, but do not expose the
	capability in st.info (yet).

	Some notes:

	It was reverted because it caused some issues with ncurses in some
	configurations, namely when using BSD padding (--enable-bsdpad, BSD_TPUTS) in
	ncurses it caused issues with repeating digits.

	A fix has been upstreamed in ncurses since snapshot 20200523. The fix is also
	backported to OpenBSD -current.
