vi: fix range selection by forward character motion

Selection of ranges for change/delete/yank by forward character
motion commands (SPACE or 'l') was incorrect.  The range was
always one character whereas vi allows the size of the range to
be specified.

Fix this by executing the motion command the required number of times.
There is a complication when the range is at the end of a line.  We need
to distinguish between a range which excludes the last character and
one which includes it.  This requires comparing the actual range with
that expected from the command count.  (With the additional quirk that
a command count of zero is equivalent to a command count of one.)
