Hmmm... an 'apropos' on 'backup' reveals:

    find-backup-file-name:
    Find a file name for a backup file, and suggestions for deletions.
    Value is a list whose car is the name for the backup file
     and whose cdr is a list of old versions to consider deleting now.

and:

    make-backup-file-name:
    Create the non-numeric backup file name for FILE.
    This is a separate function so you can redefine it for customization.

Why are there two functions?  Does one call the other?  Which is the right
one to redefine for customization?
