Fixed detection of word boundary after capital name prefix.
Examples:
* IImportWizard  matched by "import":  I[Import]Wizard
* HTMLTable      matched by "table":   HTML[Table]

The state-machine based detection turned out to be not a good fit.
Instead detect boundaries by comparing the cases in every tuple of
(previous, current, next) chars.
