You asked for an example of why this was needed; I was waiting to hear

Grammar tweaks:
If UNIQUIFY is one of the members of `secure-hash-algorithms',
Emacs constructs the nondirectory part of the auto-save file name by
applying that `secure-hash' to the buffer file name. This avoids any
risk of excessively long file names.
