[Build-common-hackers] Bug#457046: please support DEB_DH_INSTALLDOCS_ARGS_package

[Riku Voipio]

I think it would be a good idea to support DEB_DH_*_ARGS_$(cdbs_curpkg)
stanze on all supported DEB_DH_*_ARGS variables - I'd like to have
done

DEB_DH_GENCONTROL_ARGS_netcdf-doc := "-- -v1:$(DEB_VERSION)"

to set epoch only on one package, but it seems not to work, so
working it now around...

"rm -rf" only sounds scary if you don't have backups
