I don't think it's going to be a hugely important feature, but I don't see a problem with creating a new option (-C seems fine) which would have the same effect as if the arguments were contatenated into a file which is then used with -f. IIRC -c has some special characteristics which means it's probably best not to try to extend it for this feature.

ok, I'll try to write patch.
