vi: reset command count when specifying '0' range
Since commit a54450248 (vi: allow the '.' command to have a
repetition count) using '0' to specify a range doesn't work with
a non-zero repeat count, e.g. '1d0'. Users wouldn't normally try
to do that but the '.' command does.
Add a special case in get_motion_char() to handle this.
