Fix for a ZLE bug

There's been a weird bug in ZLE for a while.  The symptom is that if
one does a vi range command (e.g. cw), and the movement command moves
forward to offset 26 in the buffer, the command is applied to the
entire line instead of just the requested range.  The cause is an error
in the vi range logic.  The patch below fixes it.  I made this patch
with a beta14 patched with the ZLE changes I have already posted, but
it should apply cleanly to straight beta14 and to Zoltan's recent
releases.

Would anyone find it useful if I post all my pending ZLE changes in one
large patch?
