Correct incremental and inverted search behavior in FindReplaceDialog
Browse files Browse the repository at this point in the history 
* Makes incremental search consider the current selection if still
matching instead of moving to the next match
* Makes Shift+Enter invert search direction even if backwards search is
enabled and add regression test for that behavior
* Improves naming of IStatus#isError() to IStatus#isInputValid()
* Renames identifiers containing "FindReplacer" to "FindReplaceLogic"
