Ron Yorston 776b56d774 vi: code shrink
I was puzzled by code in find_range() which handles forward word
movement.  It included a test to see if we're at the start of a
word.  Since these are forward word movements surely we'd expect to
be at the start of a word?  In fact, the test was intended to fix a
problem with changes to the last word in a file, as discussed in the
thread starting here:

   http://lists.busybox.net/pipermail/busybox/2004-January/044552.html

The code can be simplified by testing directly for end of file instead
of indirectly for not being at the start of a word.  Since trailing
whitespace is now handled in do_cmd() the code to back up off a newline
is no longer required.
