Refactoring ensuring fSuffix is equal to length of suffix.
Refactoring ensuring fSuffix is equal to length of suffix.

While fPrefix was equal to length of prefix, in old code
fSuffix was equal to length of suffix + 1.

Made the two consistent, resulting in simplification of suffix
computation (removed "+ 1" four times, added "- 1" once).

Found inconsistency through branch coverage analysis, which
suggested that condition "fSuffix > 0" could never be false.
