Broken permissions in `.pc` quilt directory

I have a series that won't apply cleanly:

I think the fix from 181d5b0 in save_backup_file together with our

    find $ORIG_DIR -type f | xargs chmod a-w,a+r                                                                                                                                                                                                                                  

in scripts/sequence-patch.sh won't play along.

I think the change in save_backup_file is unnecessary -- i.e. just keep umask default for backup files. I may try that if I get hold of the testsuite.
