* exceed the threshold prevents further measurements being made):
*
- * 4a. Comparsion of string lengths: String lengths must be within given bounds
+ * 4a. Comparison of string lengths: String lengths must be within given bounds
* to satisfy the user-supplied similarity constraint. A negative result avoids
* invoking the O(m * n) behaviour of LCS at the cost of O(m + n) in the two
* strlen() invocations.
