re-inserted a line from the old version.  Change ((--i)) to ((++i)) in the
`else' inside the `while' loop.  Sorry about that.

That's why I had to the goofy bit with ((NUMERIC=_ilw_count+1)) in my
revised version.  That makes up-history go up the correct number of lines,
and down-history go back down the correct number.
