Shouldn't the sed part of the command be referencing the environment
variable, i.e.
	for file in file?; do sed -n '1,/Copyright/p' $file >> a_file;
done

otherwise the shell will simply expand the second "file?" again and the
output file will contain n copies of the extraction from the first file
(where n is the number of files which match the "file?" pattern). As you
say, it still shouldn't cause a paging error.
