The findNextSubstringCi? function accepts a substring
atop a string and returns the location of the substring atop a
success flag. Search is from offset n+1 in string, and
ignores case.
Searching from a too-large n results in a nil success
value (not an error).
Searching from a negative n is the same as searching from
zero.
On a nil success value, start and end are undefined.
