Also less does this :)
An strace log ( strace -s 1024 -e write -o log vim)
shows:

 grep -E '\\33(=|>)' log 
 write(1, "\33[?1049h\33[?1h\33=\33[?2004h\33[?1004h", 31) = 31
 write(1, "\33[24;1H\33[K\33[24;1H\33[?1004l\33[?2004l\33[?1l\33>", 40) = 40

infocmp rxvt-basic rxvt-unicode | grep -E '(s1|kx):'
        is1: '\E[?47l\E=\E[?1l', '\E[!p'.
        rmkx: '\E>', '\E[?1l\E>'.
        rs1: '\E>\E[1;3;4;5;6l\E[?7h\E[m\E[r\E[2J\E[H', '\Ec'.
        smkx: '\E=', '\E[?1h\E='.
