Hello CJ,

Thanks for responding.

On my system, I am building vi and vim differently. In my case, I
think vi is not using the systems' terminfo whereas vim does. Anyway,
I think there is something in rxvt-unicode-256color's terminfo that
affects how the latest vim from the mercurial repo responds/behaves.

Below is my build script for vi and vim

-e 's,/\* #define FEAT_XTERM_SAVE \*/,#define FEAT_XTERM_SAVE,g'\
