Reduce cost of deletion in levenstein distance (4 -> 3)
Before this patch, a character deletion has the same cost as 2 swaps, or
4 additions, so Git prefers suggesting a completely scrambled command
name to removing a character. For example, "git tags" suggests "stage",
but not "tag".
By setting the deletion cost to 3, we keep it higher than swaps or
additions, but prefer 1 deletion to 2 swaps. "git tags" now suggests
"tag" in addition to staged.
