The '.' command repeats the last text change. When it has a
repetition count replay the change the number of times requested.
Update the stored count if it changes. For example,
3dw deletes 3 words
. deletes another 3 words
2. deletes 2 words and changes the stored count
. deletes 2 words
function old new delta
do_cmd 4746 4781 +35
