BIT: Check for sign of bitwise operation (BIT_SIGNED_CHECK)


BIT: Check for sign of bitwise operation (BIT_SIGNED_CHECK)
 This method compares an expression such as
((event.detail & SWT.SELECTED) > 0).
Using bit arithmetic and then comparing with the greater than operator can
lead to unexpected results (of course depending on the value of
SWT.SELECTED). If SWT.SELECTED is a negative number, this is a candidate
for a bug. Even when SWT.SELECTED is not negative, it seems good practice
to use '!= 0' instead of '> 0'.
