debian bug #23229 - save file permissions

Use fqname buffer 1 for restoring the save file (just like save does when
creating it) so the value won't change out from under the code in unixmain.
- Also moved a tty-specific hack in docompress_file that was causing
the 'y' response to the "keep the save file" prompt to be echoed twice.
