[FR] Add -- option to prevent interpretation of filenames with dashes

[protist]

Observed behaviour

$ touch -- a b -i
$ dragon *

The dragon window only show files a and b, using -i as the option (i.e. --icon-only).

Expected behaviour

dragon should interpret -i correctly as a file, not as an option. This could be by a -- option, i.e.

$ dragon -- *

Thanks @N-R-K! That seems to work perfectly!
