Bug 50386 Autoindent/Smart Tab in case statement
1: case SWT.TRAVERSE_ESCAPE : 2: fTableViewer.cancelEditing(); 3: e.doit= true; Pressing Tab at beginning of line 3 removes one tab character from line 3. It shouldn't. Same indentation error for Smart Return, Correct Indentation, ... for all lines which are 2+ lines after the case keyword.
