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.
