interaction between repl -cc and replcomps

Hi. I've just found that if there is no replcomps but a user specified
repl -cc or repl -nocc options, there is NO cc: line ever. But if I
copy into their appropriate location for comps file a replcomps, it comes
good.

So: is there a reason why the -cc and nocc options don't work without a
    replcomps file? could this relate to the new -group and nogroup options
    added to repl?

tested on nmh-0.2[34] and both required there to be a replcomps file before
cc: lines were added to header.

cheers
