Change GROUP-INSERT-FILE! to accept an additional argument, which
specifies the newline translation to be used for the insertion.  This
allows the compressed-file reading code to specify that the
translation being used is that appropriate for the file being
expanded.  Formerly, the wrong translation was sometimes used because
the compressed file is expanded into a temporary file, which can
reside on a file system with a different translation, and the
translation appropriate for the temporary was used.
