As I've pointed out before, another problem with macros like these is that
it is impossible to get the up and down arrows to work properly at the
start of a line.  When you leave insert mode, vi backs up one character
except if it is already at the start of the line.  Hence macros cannot tell
if you were on the first or second character.  The macros above will move
right one character as well as up or down, when invoked at the start of the
line.
