Yank multiple character bug in VI

[Wakko Warner]

When editing a file, typing #yl where # is > 1, only 1 byte is yanked.  Same
is true for #dl except that only 1 character is deleted.  Replacing "l" with
"h" works for yanking/deleting X amount of characters left of the cursor.

vim-tiny 2:7.3.429-2 in debian works as expected.

Tested with busybox v1.20.0 and
git with commit a5ee090e8651692545514a81a16c6cde3a2dc577 (Which was the
latest when I cloned today)
