Unknown warning flag: DuplicateInterfaceFiles. See --help=warning.
Agda 2.6.4 does not now about this future warning (will enter in 2.7).
I think we should only fail softly here. Warn about the unknown warning.
This is better for forward compatibility and multi-Agda development.
Since we have --warning=error to turn all warnings into errors, folks who absolutely want to fail when an unknown warning is touched can always do so.
