Yes.  Getting the cursor position seems to be voodoo.  Unfortunately
using \e escape hard codes for one terminal type.  The above is the
popular one today but it won't work for other types such as say
hpterm.  (I didn't test hpterm but I assume not.)  But I haven't found
a better way to ge tthis info either.

I think the original plan was that if some application wanted to
position the cursor then that application must position and track the
position itself completely.  Like the way the curses library does it.
Then it will know where the cursor is later because it placed the
cursor there, obviating the need to ask the terminal where the cursor
happens to be at the moment.
