-D and -R options are mutually exclusive actually but many commands can accept them at the same time and process them differently(e.g. chattr alway chooses -D option or cowextsize accepts the last one specified), so make these commands have the consistent behavior that don't accept them concurrently. 1) Make them incompatible by setting argmax to 1 if commands can accept single option(i.e. lsattr, lsproj). 2) Make them incompatible by adding check if commands can accept multiple options(i.e. chattr, chproj, extsize, cowextsize).
